[uf-new] Third attempt at hAudio

[Manu Sporny]

hAudio has been updated:

* Noted that hAudio deals with individual audio recordings
* Removed any reference to grouping
* Updated to match the latest discussions on the list
* Many other small edits and cleanups

http://microformats.org/wiki/audio-info-proposal

Most everything that was under contention has been removed from the
latest haudio proposal. Constructive feedback from this list would be
great...
