Rise of the Triad X (ROTTX) V1.2

Whats New:

- Rewrote SDL_Mixer for Xbox which results in..
- Music
- Much improved sound FX


Just patch these files over your existing ROTT files. 
If your a new user remember to grab the ROTT 1.0 archive.

If you prefer better sounding soundpatches for Timidity
feel free to try them out.

SDL_Mixer works great. I will release this as a seperate lib
for other developers...maybe even port SDL completely ;)
