- moved the VP8 decoding loop into the movie player class and got rid of animvpx.
This allowed significant simplification of code data and many of the error checks could also be simplified because this player doesn't really need it all. Also use nanoseconds to count frame delays, not milliseconds, as milliseconds can cause timing anomalies with common frame rates very easily.
