First cut at Exit Fullscreen bubble on Linux.

It shows and disappears after 3 seconds.  There is no way to bring it
back.

The following remain to be done:
- Rounding the bottom corners (with a radius of 8, ActAsRoundedWindow
  looks ugly) and make it transparent.
- Slide in/out animation.
- Implement the logic in the Windows version for when to show or hide the
  bubble.  It's pretty complicated and I haven't decided whether to
  port it or to try to share it.
