Decided to rewrite the audio library, new audio library is called
winterAudioLib. Old lib will remain for reference until the new library is
done. Also fixed small error in CG shader which broke the cg shader on AMD
targets.
Removed old audio classes from new library.
Renamed AudioFileTypes to AudioFile which is the base class for each audio
file format. Also started with setting up the sounds and effects. The
idea is that each sound has a chain of effects that will be applied on the
sound buffer.
