Initial commit of work-in-progress MPEG video player plugin based on libmpeg2. Works on all targets with colour LCDs, but most optimised for the ipod Color/Photo and Nano. It currently only plays raw MPEG-1 or MPEG-2 video streams (no audio). Also adds a new lcd_yuv_blit() function to the plugin API - currently only implemented for the ipod Color/Photo and Nano.
