* AUDIO_SAMPLE
* remove unused variable iLoops from the struct
* rename bRemove to the more descriptive title of bFinishedPlaying
* change sound_SetupChannel to return a BOOL rather than be return void and throw its output value in a pointer
* make audio_Update() return void (instead of BOOL) since its output value was TRUE always anyway, plus all its callees ignored the output value
* increase readability of lots of functions in audio.c
* remove unused (and nothing doing) functions: audio_StopTrack, audio_SetTrackPan, audio_SetTrackVol and audio_SetTrackFreq
