Audio player resampling

Today I managed to get resampling in the audio player working, including resolving two particularly nasty bugs:

• An integer math overflow when resampling using a large sinc curve causing crashes.
• A slight math error in the down sampling routines causing a very slight "ringing" noise in the output signal.

Also, the audio player now works when the audio engine is in 64-bit audio mode. This required updating my resampling library to be 64-bit audio capable as well.

Next is getting it to a route to a rack rather than output, then integrating it with the offline renderer.
