Bug 1348396 - Only show a badge on PanelUI while in fullscreen r=enndeakin+6102

Previously we were showing a doorhanger when the user moused to the
top of the screen while in fullscreen mode. However, the doorhanger
would disappear before the user had a chance to interact with it.
We decided it's best anyway to simply display a badge when the user
is in fullscreen, and to reshow the doorhanger when the user exits
fullscreen.
