More Audio goodness

I've just added extra functionality to the Audio handlers in Red9 that hopefully you'll all find useful. 

Firstly I've expanded on the conversion tools to handling timecode, we now have the full complement:

milliseconds_to_Timecode(milliseconds, smpte=True, framerate=None)
milliseconds_to_frame(milliseconds, framerate=None)
timecode_to_milliseconds(timecode, smpte=True, framerate=None)
timecode_to_frame(timecode, smpte=True, framerate=None)
frame_to_timecode(frame, smpte=True, framerate=None)
frame_to_milliseconds(frame, framerate=None)

We're using these internally to process timecode around our MoCap deliveries, converting time to the relevant units as and when required.

I've also added a new function to the Red9_Sound menu in the Trax Editor, 'Sync_BWavs' which is designed to automatically sync multiple BWav files to their internal timecode. BWav's are Braodcast Wav's used when recording audio with timecode as it embeds the data into the wav's header, very useful in production.

The new function processes either the selected audio nodes in Trax, or ALL wavs in the scene, depending on selection. It then inspects the internal BWav's timecode, and if found and valid it will shift the audio nodes in Maya to match their original timecode's, re-syncing them to the original shoots timelines. 

I've also done a few fixes to the AudioNode class, adding the setters that were missing in some of the properties.

cheers
