First stage

get webm sorta working on the existing model
problem: no seek (seek needs sync io)
problem: doesn't run to completion (don't know when done/not done)
problem: we don't report frame rate (can't rely on it existing in webm)
problem: audio not yet working
fixed
problem: we don't report audio timestamps properly?
fixed
problem: webm demuxing super slow on IE (from extra copies?)
fixed

Second stage

kill fps as a fixed quantity
replace with presentation timestamps and a dynamic rate monitor for stats

Third stage

rework io model to allow sync stuff
enable webm seek using nestegg
re-enable ogg seek from the C side? ** use liboggz for the chop?
