[theora] Ogg index and Skeleton 4.0

Not yet, I've only added a 32bit radix and the Role, and Name message 
header fields.

I assume that a 32 bit unsigned integer would be sufficient for the 
predelay field, and that you want it in the fisbone packet? Or can we 
get away with a 16 bit unsigned int?


All the best,
Chris P.
