Introduce a new class, EventEmitter, which implements signal
handling for pure JavaScript classes. EventEmitter still
utilizes GJS' addSignalMethods internally.
EventEmitter allows static typechecking to understand the
structure of event-emitting JS classes and makes creating
child classes simpler.
The name 'EventEmitter' mirrors a common name for this pattern
in Node and in JS libraries.

We have made good progress on object literals as well, although there
are still a lot that use the old style, given how ubiquitous object
literals are.
But the needed reindentation isn't overly intrusive, as changes are
limited to the object literals themselves (i.e. they don't affect
surrounding code).
And given that object literals account for quite a bit of the remaining
differences between regular and legacy rules, doing the transition now
is still worthwhile.

This ports the runDialog changes of [1] to the underlying history
component, where they can benefit looking glass as well: the history is
now responsible for trimming the input and deciding that it shouldn’t be
stored if empty. (Note that _setPrevItem and _setNextItem already
skipped updating the history if the entry was empty.)
Since both users, runDialog and lookingGlass, also need the trimmed
input for other reasons – runDialog to avoid issues when interpreting
the command as a file path (if it can’t be executed as a command),
lookingGlass to decide whether a command should be run at all – have
addItem return the trimmed input. (runDialog and lookingGlass are not
yet changed to take advantage of this – that will be done in separate
commits.)

ES6 finally adds standard class syntax to the language, so we can
replace our custom Lang.Class framework with the new syntax. Any
classes that inherit from GObject will need special treatment,
so limit the port to regular javascript classes for now.

Whenever a command runs in the run dialog, it
will be added to the history unless it is
already the last entry. This does not apply
for entries that are not consecutive, which can
result in long chains of commands which
alternate, e.g. lg, r, lg, r, lg, r. Not only is
this wasteful in terms of space, but also
inconsistent with how history works elsewhere,
e.g. in the shell.
Therefore, remove entries in the history that are
equal to the one that will be added to the end of
of the history when the entry already exists.

When not using arrow notation with anonymous functions, we use Lang.bind()
to bind `this` to named callbacks. However since ES5, this functionality
is already provided by Function.prototype.bind() - in fact, Lang.bind()
itself uses it when no extra arguments are specified. Just use the built-in
function directly where possible, and use arrow notation in the few places
where we pass additional arguments.

Any symbols (including class properties) that should be visible
outside the module it's defined in need to be defined as global.
For now gjs still allows the access for 'const', but get rid of
the warnings spill now by changing it.

We only use lastItem() to reset the history index to the end, so
nobody noticed the utter nonsense in the return value until gjs
started to warn about it. As we don't actually use the value
anywhere, we could just remove it, but the function name implies
that an item is returned, so fix it to behave as advertised.

Currently the HistoryManager consumes all arrow up/down key presses
unconditionally. Change this to only consume the event if the entry
text was actually changed, e.g. not when trying to move past the
first/last item.

The last patch in the sequence. Every place that was previously
setting prototype has been ported to Lang.Class, to make code more
concise and allow for better toString().

js2-mode is no longer developed and we recommend js-mode these days,
so switch the modelines to specify that, and make them consistent
across all files.

If the user typed "a", hit up, and pressed enter again, we wouldn't re-set the
history pointer to the end, so the broken navigation would instead go to the
entry before that.

Make GSettings support optional, refactor text entry handling,
fix some off-by-one bugs in the management itself, use Params
for parsing, fix other typos and bugs.

runDialog and lookingGlass both implement a home-made history
manager, each working slightly differently than each other in
behavior and implementation.
Extract the behavior and implementation from runDialog, which
reads and saves to GSettings.
