M:Robe 500i: More LCD initialization, and beginnings of support for QVGA as well as VGA on the LCD. MPEGPlayer now works with reasonable performance on smaller videos, but YUV blitting persists after MPEGPlayer is left, some cleanup/changes to the initialization code. This should be functionally equivalent for the ZVM, but the #ifdef's may need to be added back for app.lds. Get the bootloader building again.
