Brickmania for Sansa c200 and the small H10 with new graphics. While at it reduce the number of necessary per screen definition by letting the plugin retrieve the bitmap heights and widths from the file, therefore 'clean up' some graphics e.g. the menu items one, also make some backgrounds a bit nicer. Rearrange bitmaps/native/SOURCES and rename some graphics to reduce the number of duplicated bitmaps which only had a different name e.g. the ball -  and tweak the gameover bitmap (on colour displays it uses transparency, and adapt the already existing mono bitmap to be usable). There might be minor differences in the 'looks' for existing ports but almost not noticeable with the exception that the gameover graphic is now centered. Introduce an alternative left and right key for c200 (volume up/down) for easier control. Manual update will follow.
