SPU2Ghz: Made the timestretcher automatically turn on/off based on game speed. This is possible thanks to recent changes by Jake.Stine :) 

The way it works now, it makes it completely automatic for the user.
If the buffers over/underflow the stretcher enables itself.
Once it decides that game speed is fine again, it disables itself.

This works really great here, but please comment if it causes trouble for you.
