sound effects

Added the sound routines along with a few cheesy sound effects. Will revise those later. I'm using only channel 1 due to the digitized sample support, which requires AUDV0 to be updated on just about every scan line (it's using a variation of DPC+'s 3-voice music routine). I have some ideas on how to work around this for users with an AtariVox plugged in. I might even be able to make it work when there's no speech being played back.

Tweaked the WallAvoidance routines, in the prior routines the robots would almost always run into the end of a wall. That should now be 1/8th the time.

Decolored the robots to spur on Color Combination Contributions.
