Handle global keybindings in the shell

Handling global keybindings, such as volume and brightness keys
but also custom keybindings, directly in the compositor is the only way
to deal with grabs and modal operations that could be active (primarily
the overview, for which special policy was introduced in the last
commit)

+Coding guide
+============
+
+Our goal is to have all JavaScript code in GNOME follow a consistent style. In
+a dynamic language like JavaScript, it is essential to be rigorous about style
+(and unit tests), or you rapidly end up with a spaghetti-code mess.
+
+A quick note
+------------
+
+Life isn't fun if you can't break the rules. If a rule seems unnecessarily
+restrictive while you're coding, ignore it, and let the patch reviewer decide
+what to do.
+
+Indentation and whitespace
+--------------------------
+
+Use four-space indents. Braces are on the same line as their associated
+statements.  You should only omit braces if *both* sides of the statement are
+on one line.
+
+* One space after the `function` keyword.  No space between the function name
+* in a declaration or a call.  One space before the parens in the `if`
+* statements, or `while`, or `for` loops.
+
+    function foo(a, b) {
+        let bar;
+
+        if (a > b)
+            bar = do_thing(a);
+        else
+            bar = do_thing(b);
+
+        if (var == 5) {
+            for (let i = 0; i < 10; i++) {
+                print(i);
+            }
+        } else {
+            print(20);
+        }
+    }
+
+Semicolons
+----------
+
+JavaScript allows omitting semicolons at the end of lines, but don't. Always
+end statements with a semicolon.
+
+js2-mode
+--------
+
+If using Emacs, do not use js2-mode. It is outdated and hasn't worked for a
+while. emacs now has a built-in JavaScript mode, js-mode, based on
+espresso-mode. It is the de facto emacs mode for JavaScript.
+
+File naming and creation
+------------------------
+
+For JavaScript files, use lowerCamelCase-style names, with a `.js` extension.
+
+We only use C where gjs/gobject-introspection is not available for the task, or
+where C would be cleaner. To work around limitations in
+gjs/gobject-introspection itself, add a new method in `shell-util.[ch]`.
+
+Like many other GNOME projects, we prefix our C source filenames with the
+library name followed by a dash, e.g. `shell-app-system.c`. Create a
+`-private.h` header when you want to share code internally in the
+library. These headers are not installed, distributed or introspected.
+
+Imports
+-------
+
+Use UpperCamelCase when importing modules to distinguish them from ordinary
+variables, e.g.
+
+    const GLib = imports.gi.GLib;
+
+Imports should be categorized into one of two places. The top-most import block
+should contain only "environment imports". These are either modules from
+gobject-introspection or modules added by gjs itself.
+
+The second block of imports should contain only "application imports". These
+are the JS code that is in the gnome-shell codebase,
+e.g. `imports.ui.popupMenu`.
+
+Each import block should be sorted alphabetically. Don't import modules you
+don't use.
+
+    const GLib = imports.gi.GLib;
+    const Gio = imports.gi.Gio;
+    const Lang = imports.lang;
+    const St = imports.gi.St;
+
+    const Main = imports.ui.main;
+    const Params = imports.misc.params;
+    const Tweener = imports.ui.tweener;
+    const Util = imports.misc.util;
+
+The alphabetical ordering should be done independently of the location of the
+location. Never reference `imports` in actual code.
+
+Constants
+---------
+
+We use CONSTANTS_CASE to define constants. All constants should be directly
+under the imports:
+
+    const MY_DBUS_INTERFACE = 'org.my.Interface';
+
+Variable declaration
+--------------------
+
+Always use either `const` or `let` when defining a variable.
+
+    // Iterating over an array
+    for (let i = 0; i < arr.length; ++i) {
+        let item = arr[i];
+    }
+
+    // Iterating over an object's properties
+    for (let prop in someobj) {
+        ...
+    }
+
+If you use "var" then the variable is added to function scope, not block scope.
+See [What's new in JavaScript 1.7](https://developer.mozilla.org/en/JavaScript/New_in_JavaScript/1.7#Block_scope_with_let_%28Merge_into_let_Statement%29)
+
+Classes
+-------
+
+There are many approaches to classes in JavaScript. We use our own class framework
+(sigh), which is built in gjs. The advantage is that it supports inheriting from
+GObjects, although this feature isn't used very often in the Shell itself.
+
+    const IconLabelMenuItem = new Lang.Class({
+        Name: 'IconLabelMenuItem',
+        Extends: PopupMenu.PopupMenuBaseItem,
+
+        _init: function(icon, label) {
+            this.parent({ reactive: false });
+            this.addActor(icon);
+            this.addActor(label);
+        },
+
+        open: function() {
+            log("menu opened!");
+        }
+    });
+
+* 'Name' is required. 'Extends' is optional. If you leave it out, you will
+  automatically inherit from Object.
+
+* Leave a blank line between the "class header" (Name, Extends, and other
+  things)  and the "class body" (methods). Leave a blank line between each
+  method.
+
+* No space before the colon, one space after.
+
+* No trailing comma after the last item.
+
+* Make sure to use a semicolon after the closing paren to the class. It's
+  still a giant function call, even though it may resemble a more
+  conventional syntax.
+
+GObject Introspection
+---------------------
+
+GObject Introspection is a powerful feature that allows us to have native
+bindings for almost any library built around GObject. If a library requires
+you to inherit from a type to use it, you can do so:
+
+    const MyClutterActor = new Lang.Class({
+        Name: 'MyClutterActor',
+        Extends: Clutter.Actor,
+
+        vfunc_get_preferred_width: function(actor, forHeight) {
+             return [100, 100];
+        },
+
+        vfunc_get_preferred_height: function(actor, forWidth) {
+             return [100, 100];
+        },
+
+        vfunc_paint: function(actor) {
+             let alloc = this.get_allocation_box();
+             Cogl.set_source_color4ub(255, 0, 0, 255);
+             Cogl.rectangle(alloc.x1, alloc.y1,
+                            alloc.x2, alloc.y2);
+        }
+    });
+
+Translatable strings, `environment.js`
+--------------------------------------
+
+We use gettext to translate the GNOME Shell into all the languages that GNOME
+supports. The `gettext` function is aliased globally as `_`, you do not need to
+explicitly import it. This is done through some magic in the
+[environment.js](http://git.gnome.org/browse/gnome-shell/tree/js/ui/environment.js)
+file. If you can't find a method that's used, it's probably either in gjs itself
+or installed on the global object from the Environment.
+
+Use 'single quotes' for programming strings that should not be translated
+and "double quotes" for strings that the user may see. This allows us to
+quickly find untranslated or mistranslated strings by grepping through the
+sources for double quotes without a gettext call around them.
+
+`actor` and `_delegate`
+-----------------------
+
+gjs allows us to set so-called "expando properties" on introspected objects,
+allowing us to treat them like any other. Because the Shell was built before
+you could inherit from GTypes natively in JS, we usually have a wrapper class
+that has a property called `actor`. We call this wrapper class the "delegate".
+
+We sometimes use expando properties to set a property called `_delegate` on
+the actor itself:
+
+    const MyClass = new Lang.Class({
+        Name: 'MyClass',
+
+        _init: function() {
+            this.actor = new St.Button({ text: "This is a button" });
+            this.actor._delegate = this;
+
+            this.actor.connect('clicked', Lang.bind(this, this._onClicked));
+        },
+
+        _onClicked: function(actor) {
+            actor.set_label("You clicked the button!");
+        }
+    });
+
+The 'delegate' property is important for anything which trying to get the
+delegate object from an associated actor. For instance, the drag and drop
+system calls the `handleDragOver` function on the delegate of a "drop target"
+when the user drags an item over it. If you do not set the `_delegate`
+property, your actor will not be able to be dropped onto.
+
+Functional style
+----------------
+
+JavaScript Array objects offer a lot of common functional programming
+capabilities such as forEach, map, filter and so on. You can use these when
+they make sense, but please don't have a spaghetti mess of function programming
+messed in a procedural style. Use your best judgment.
+
+Closures
+--------
+
+`this` will not be captured in a closure, it is relative to how the closure is
+invoked, not to the value of this where the closure is created, because "this"
+is a keyword with a value passed in at function invocation time, it is not a
+variable that can be captured in closures.
+
+All closures should be wrapped with a Lang.bind.
+
+    const Lang = imports.lang;
+
+    let closure = Lang.bind(this, function() { this._fnorbate(); });
+
+A more realistic example would be connecting to a signal on a method of a
+prototype:
+
+    const Lang = imports.lang;
+    const FnorbLib = imports.fborbLib;
+
+    const MyClass = new Lang.Class({
+        _init: function() {
+            let fnorb = new FnorbLib.Fnorb();
+            fnorb.connect('frobate', Lang.bind(this, this._onFnorbFrobate));
+        },
+
+        _onFnorbFrobate: function(fnorb) {
+            this._updateFnorb();
+        }
+    });
+
+Object literal syntax
+---------------------
+
+In JavaScript, these are equivalent:
+
+    foo = { 'bar': 42 };
+    foo = { bar: 42 };
+
+and so are these:
+
+    var b = foo['bar'];
+    var b = foo.bar;
+
+If your usage of an object is like an object, then you're defining "member
+variables." For member variables, use the no-quotes no-brackets syntax: `{ bar:
+42 }` `foo.bar`.
+
+If your usage of an object is like a hash table (and thus conceptually the keys
+can have special chars in them), don't use quotes, but use brackets: `{ bar: 42
+}`, `foo['bar']`.
+
+Getters, setters, and Tweener
+-----------------------------
+
+Getters and setters should be used when you are dealing with an API that is
+designed around setting properties, like Tweener. If you want to animate an
+arbitrary property, create a getter and setter, and use Tweener to animate the
+property.
+
+    const ANIMATION_TIME = 2000;
+
+    const MyClass = new Lang.Class({
+        Name: 'MyClass',
+
+        _init: function() {
+            this.actor = new St.BoxLayout();
+            this._position = 0;
+        },
+
+        get position() {
+            return this._position;
+        },
+
+        set position(value) {
+            this._position = value;
+            this.actor.set_position(value, value);
+        }
+    });
+
+    let myThing = new MyClass();
+    Tweener.addTween(myThing,
+                     { position: 100,
+                       time: ANIMATION_TIME,
+                       transition: 'easeOutQuad' });
