- cleaned up the pitch management in the sound backend.

Browse source 
This now treats all pitch methods equally instead of the preferential treatment of Doom's original pitch hack. Most importantly, the sound channel now stores the pitch as a floating point value instead of 9.7 fixed point.
snd_pitched now also gets checked in the sound engine, not the low level interface.
