Fix several issues around fullscreen Mac plugins:

* Keystrokes are now properly sent to plugins in fullscreen mode
* When a plugin creates a fullscreen window, we hide the menu bar and restore it when the window is closed
BUG=19534,21020
TEST=Open a page with plugins that can go full screen (example: flash video players).  Enter full screen mode and verify that esc, arrow keys, spacebar, etc. work as expected.  Verify that the menu bar is hidden when the plugin goes fullscreen and is restored when it exits fullscreen mode.
