[MPlayer-cygwin] Change priority to realtime in windows

Raising thread priority does help with multimedia applications.  I have not 
actually tested this on mplayer, but my old K6-2 400MHz would play dvd's 
smoothly if I upped the thread priority and jerky if I didn't.  It can make a 
difference, but it is screwing with your OS so it may have undesired 
side-effects.
