Added new mouse-is-locked bezel, which is displayed when statusbar is hidden.
Re-added mouse-lock toggle button to statusbar. Reworded UI text to refer to "mouse pointers" instead of just "mice".
Moved mouse-lock until after the transition to fullscreen is over, to avoid bezel appearing and flickering during transition.
Made ADBFullscreenCapableWindow's "inFullscreenTransition" flag properly reflect that state during Lion's fullscreen transitions. Fixed the latent fuckups this revealed.
Set statusbar to be hidden by default.
