docutils: updating to 0.10

mplayer2 required "rst2man.py", not available in 0.5.
ffmpeg 1.1: building libavresample

It's disabled by default, but mplayer2 requires it (still).
Adding mplayer2, a mplayer fork.

It can play files very well with "vdpau". It has a reworked
vdpau pipeline compared to mplayer1. Mplayer1 fails to play well in
my computer.
