#58 Port to Palm OS

[Cuzog]

I know that SDL natively doesn't work on Palm, but I have seen
several games made with SDL move over to Palm before. Palm
does not handle multiple threads, so that is a potential barrier.
Perhaps the threading could be simulated.

SDL for Palm is being developed here: http://www.emuboards.com/
