Sound improvements for rockboy - players now sync the sound (The gigabeat now plays at a steady 60 fps as long as the frameskip is set properly). If a new sample is not available a blank buffer is used. All devices use 44.1 kHz for gameboy sound now so no more high pitched sounds. Added a screen rotation option. Removed unscaled code for devices with a screensize smaller than the gameboy. All buttons are now configurable. Scroll wheel devices still have button configuration problems though.
