Update issue #211 : Process main window keyboard shortcuts in EVR video renderer window in normal or fullscreen mode
Allows stopping full screen playback, playback control, switching windows etc. 
One annoying issue : when starting full screen playback something seems to be stealing focus - before using keyboard shortcuts you have to click on the full screen video.
