Move FPS display out of video_out_rockbox.c and into mpegplayer.c. Also add frame-rate limiting and frame-skipping (skipping display only, not decoding) to try and achieve real-time playback. Frame-rate limiting and frame skipping (and FPS display) are enabled via options in a new menu and are currently all off by default.
