Patch from begasus to allow building under haiku and beos. The program is crashing when you launch it (segmentation violation).

I'm not sure the way to get the program directory we use is ok for beos, but the official way of doing that is using C++ code.
Maybe it's time to switch to some more unix way to store the config files...

This should also fix watcom build (very untested as i'm using mingw to cross compile windows builds now)
Also added begasus to the credits screen.
