Initial WVS for mpegplayer. Adjusts to the user's preferred font and uses FF/RW preferences set for playback. Picked a random color for the base WVS color but it could be configured. Some engine tweaks to accomodate it since certain nescessities are clearer now. Fix a clipped YUV output bug in the SIM.
