GrabHelper automatically releases grabs when the user clicks outside
the grabbed actors. However at least for the message-tray (which is
the only user of grabHelper at the moment), we must ignore any events
from the On-Screen-Keyboard, to prevent the tray from hiding at every
key press.

This fixes a case of _updateState() being called recursively,
resulting in stray grab()/ungrab() calls the leave the entire
desktop in a stuck focus state.

The message tray is now modal and pushes the view up, but the keyboard
is shown below it. Solve this by applying a special styling to the
keyboard and message tray combination, and by not pushing the windows
up when the keyboard is shown.

When changing the user's avatar image, AccountsService will
overwrite the old image with the new one, so the location
returned by get_icon_file() is always the same.
In order to pick up the change, we need to make sure to clear the
previous image from both StTextureCache and StThemeNode's paint
cache.

For performance reasons, resources required to paint a widget are
aggressively cached; we know of at least one case where our caching
prevents updating the used background-image correctly, so add explicit
API to clear all associated cache data.

StThemeNode caches its resources aggressively to keep the required
work on paint to a minimum - right now, resources are only recreated
on allocation changes.
In order to update the background-image property correctly when the
underlying file changes, resources need to be recreated without a
size change, so add an explicit method for that.

The current API assumes that image data loaded from files remains
valid during the life time of the shell. This assumption is mostly
valid for image files we provide ourselves (with the exception being
designers working on those files), but not necessarily for "external"
files - provide API to explicitly remove cached data associated with
a URI for those cases.
