The settings in org.gnome.desktop.default-applications.at
have been removed, use the corresponding settings 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.
