This dramatically thins down and sanitizes the application code.
The ShellAppSystem changes in a number of ways:
* Preferences are special cased more explicitly; they aren't apps,
they're shortcuts for an app), and we don't have many of them, so
don't need e.g. the optimizations in ShellAppSystem for searching.
* get_app() changes to lookup_app() and returns null if an app isn't
found. The semantics where it tried to find the .desktop file
if we didn't know about it were just broken; I am pretty sure no
caller needs this, and if they do we'll fix them.
* ShellAppSystem maintains two indexes on apps (by desktop file id
and by GMenuTreeEntry), but is no longer in the business of
dealing with GMenuTree as far as hierarchy and categories go. That
is moved up into js/ui/appDisplay.js. Actually, it flattens both
apps and settings.
Also, ShellWindowTracker is now the sole reference-owner for
window-backed apps. We still do the weird "window:0x1234beef" id
for these apps, but a reference is not stored in ShellAppSystem.
The js/ui/appDisplay.js code is rewritten, and sucks a lot less.
Variable names are clearer:
_apps -> _appIcons
_filterApp -> _visibleApps
_filters -> _categoryBox
Similarly for function names. We no longer call (for every app) a
recursive lookup in GMenuTree to see if it's in a particular section
on every category switch; it's all cached.
NOTE - this intentionally reverts the incremental loading code from
commit 7813c5b93f. It's fast enough
here without that.

In commit 9bd22dc0, I introduced an API to load an arbitrary
.desktop file, not necessarily from the menu path. It turns
out this function was broken because it created ShellApp instances
that were *different* from ones that were cached normally.
As far as I can tell, we didn't initially use it. Then later
Util.spawnDesktop was created which used this function.
Remove this broken function and all callers; if we're loading
.desktop files from *outside* the menu path, we can look at
readding.
This patch also kills off Util.spawnDesktop in favor of callers
talking to ShellAppSystem directly, now that the latter reports
errors.

If the Shell is started with HighContrast enabled, it will never
see another value for the GSettings keys. In that case, we just
reset to the default.

The setting in org.gnome.desktop.default-applications.at
has been removed, use the corresponding setting in
org.gnome.desktop.a11y.applications instead.

gsettings-desktop-schemas had two conflicting settings for showing
the magnifier: 'show-magnifier' in org.gnome.desktop.a11y.magnifier
and 'screen-magnifier-enabled' in org.gnome.desktop.a11y.applications.
The former has been removed in favor of the latter, so adjust to this
change.
Add Util.spawn, Util.spawnCommandLine, and Util.spawnDesktop for
spawning a command/argv/.desktop file in the background, automatically
handling errors via MessageTray.SystemNotificationSource(), and
Util.trySpawn, Util.trySpawnCommandLine, and Utils.trySpawnDesktop
that don't do automatic error handling (but do at least clean up the
error message in the exception a bit).
Update various other bits of code around the shell to use the new
methods.

The magnifier should be enabled/disabled via the appropriate
GSettings key - otherwise the setting gets out of sync with the
actual state of the magnifier.

gnome-settings-daemon has moved to GSettings for most settings, we
should adapt as well. The only remaining GConf key is for metacity
(visual bell).

Introduce the Universal Access status indicator as designed, modeled
after the similar UI provided by g-s-d. This indicator allows the user
to change rapidly the keyboard and mouse behaviour (sticky keys, slow
keys, bounce keys, mouse keys), as well as the enabled ATs (magnifier,
screen reader, screen keyboard) and the HighContrast Gtk theme.
