[theora] Key frame bitrate

[Andreas Engel]

This sounds like a good idea. If you have a patch working for theora 
1.1.1 I would sure like to test it. But I need the possibility to 
connect to a running stream without getting garbage at the start. In the 
current version I just have to wait for the first key frame. How can 
this be done with "rolling intra" ?
