Updated version of No Gravity. This time endian problem should be fixed. At
least colours are OK now here.

Thanks to Stephane Denis who fixed the code :) 

To run the game, you need data files from:

http://www.realtech-vr.com/nogravity/

"nogravity.rmx" should be in the same directory as the executable.

Nogravity uses only SW rendering currently, and it uses SDL + SDL_Mixer +
many other libraries as well.
