CD32 Frog Feast updates.

I've added most of the functionality of the latest Frog Feast game to the CD32 version. I still need to clip the sprites at the edge of the screen and add sound and music support. I'm hoping to wrap up this version in the next week or so.

I am having some problems running the program on a CDTV. I'm not sure what the problem is. It loads up and displays the title screen, but there seems to be some issue with the blitter.
