Mostly kinda fixed up keyboard issues for EZGames.

They can add their keyboard listeners directly to the GameControl object
to receive global key events.

There are strange focus weirdnesses on the flex side- sometimes you have
focus with no focus highlight and sometimes you don't have focus and you
do have the highlight. Punting, rather than spending more hours on this.
