Follow-ups/Tweaks for Embedded Flash Fullscreen.
1. Added mouse lock support for the embedded flash fullscreen widget using the existing Flash-privileged mechanism.
2. Removed the redundant "Press Esc to Exit Fullscreen" balloon pop-up, in favor of Flash's built-in message.
3. Fixed bug where the status bubble/tooltip (at lower-left) was not being hidden while in fullscreen mode.
Testing: Ran unit tests. Manually confirmed all of the above work as intended both with *and* without the --embed-flash-fullscreen command-line flag. Tested on Linux/Win Aura, Mac, and Win non-Aura.
