This probably should have been two separate patches.  (Sorry, the author was new to git.)

1. Adds isHiding field to _ClutterStageOSX to allow windowDidResignKey delegate to not order full screen window back whilst the full screen window was being hidden.  This caused other application windows to be hidden (and to remain hidden after full screen mode was exited.)

2. Adds code to keep hidden stage windows from being listed in the application's Windows menu. (Possibly an enhancement rather than a bug fix.)


Patch is here: (accidentally committed .c and .h separately)
