[MPlayer-dev-eng] Fix for Mplayer -slave mode

[Jesse L. Zamora]

Hello,

Here's a very small patch that fixes the -slave mode in Mplayer; when Mplayer 
is being used as a backend for an application and the user presses q or Esc, 
Mplayer gets the key press and closes. This fix is VERY simple and I've tested 
it for countless hours with my program (LinTV) and there doesn't seem to be 
any problems with it. Please review!
