The classic style is decidedly lower contrast than the default
style, so the high-contrast variant could prove really useful
here. However for now, just override the default icon style as
in the default session.

setThemeStylesheet() stopped accepting %null to revert to the default
stylesheet. The issue is fixed in gnome-shell master, but work around
it for 3.15.2 to not ship broken (again).
Move messageTray patching form the Extension object to the WindowList
class. Moreover, only do the patching if the window list is on the bottom
monitor. This refactoring will make it easier to have several instances
of WindowList (one on each monitor).

Currently when using auto-grouping, the list is ungrouped each
time a window is closed, and then possibly re-grouped on the next
allocation - as a result, there is a brief "ungroup flash" if the
list is supposed to remain grouped.
Avoid this by computing the width the ungrouped list would have
rather than by actually ungrouping it.

Since commit 191c7ccc24, we check whether we already have a window
in the list before re-adding it on MetaWorkspace::window-added.
We can do something similar on MetaWorkspace::window-removed to
avoid some extra work when a window is moved between workspaces
rather than destroyed.
The list returned may contain windows that are being destroyed.
The ShellGlobal method filters those out, so use that instead; we
should eventually stop looking at window actors when we want windows,
but for now this is the easy and safe thing to do.
Rather than re-implementing the function (and risk missing improvements
like the launch animation), call the original one as if the user had
middle-clicked the launcher.
We do need to inject our own handler to treat application-switch
actions the same way as the corresponding window-switch ones;
we can actually express exactly this without re-implementing the
entire function, by calling the original handler with a tweaked
action parameter - the resulting code is not only more concise,
but should also be a bit more robust against changes in core.

Since shell commit dd85670f8b25, the handler got a return value to
determine whether Escape should be handled automatically; we do
want this for the window switcher, so add an appropriate return
value to restore the expected behavior.
