Title: Cleanup of documentation for SoundEffectInstance and misc code cleanup.

Cleanup of documentation for SoundEffectInstance. Removed unnecessary hold on the parent SoundEffect reference. Removed a duplicate initialization of the source buffer. Changed the use of Math.exp in the pitch conversion code to use Math.pow so that it can be understood better.
