MaxMod sound engine lib integration

Browse Source 
This commit integrates the MaxMod sound engine into PTGB.

Some test code already existed, but now it's done for real.

I added a thin API wrapper in sound.c/sound.h to abstract the sound engine.

One of AquaticAlloy's test songs was added to the main menu as a proof of concept.
We may want to disable it before the actual merge though.
