Currently adding a new session mode requires patching the sources.
As defining custom modes can be desirable in some circumstances
(for instance for administrators of kiosk setups), load additional
modes from JSON files.

Now that we use the new 'switch-applications' keybinding for the
application-based alt-tab popup, we can use the 'switch-windows'
keybinding for a more traditional switcher.
Based heavily on the alternate-tab extension from Giovanni Campagna.

The Shell's alt-tab popup is application-based, so using the
'switch-windows' keybinding for it never really made sense.
Use the newly added 'switch-applications' keybinding instead.

If the chosen action is not open, the tray should not be closed, to
let the user further interact with it (for example to mute or remove
more sources)

This is meant to expose the global.session_mode to applications such
as the gnome-tweak-tool, which would need it to differentiate between
the vanilla GNOME Shell mode and the fallback replacement mode.

Currently we assume that either the initial sessionMode will have
the overview or none of the pushed modes - starting without the
overview and pushing a mode that adds it fails spectacularly.
However this is exactly what we are going to do when loading external
modes asynchronously - we'll initially use the default mode while
the modes are loading, and switch to the mode passed on the command
line when finished. So make sure that the overview UI gets initialized
properly in that case.

Since commit 0c807bddaf, the run dialog no longer handles Escape
key presses itself but uses the action key mechanism of modal dialogs.
As the latter uses key-release events, our own handling of the Escape
key runs on key-press.
Fix this by bailing out early if anything has pushed a modal in addition
to the overview (like system modals, looking glass, ...).

Invalid ID errors from that function are normal, because the set
of IDs to acknowledge may not match the set in the connection manager
due to race conditions.
This is also what empathy does.

MessageTray._tween sets the state variable to the in-progress value,
so it must be sure that at the end of the animation the value will
be the corresponding final and nothing else will happen in between.

Since the introduction of overlay hover borders, there has a been
a timing disconnection between hiding the border and button, and
this creates noise and reduces the effect of the window+overlay
as a single unit.
Solve that by animating the close button too, so that the two actors
are shown and hidden always at the same time.
Also, consolidate the code to make it clear to future authors that
those two items need to stay coordinated.

Turns out that tweener has a very complex logic to decide when a new
tween on the same properties overrides completely the old, and unfortunately
what we were doing was not enough in all cases.
Just be explicit, and don't let anything else mess with the state.

On additional monitors the workspacesView takes up the entire monitor
and in some cases windows in overview can end up hard against the
edge of the monitor.

The panel should change appearance according to the sessionMode,
so add a new panelStyle sessionMode property which allows to
specify a mode specific style class for the panel actors.
