added to doc, hopefully in right section.

maybe you could reuse the code to pass options directly to
xvid and other encoders, and just make it a generic option '-vleopts' or
just '-vleo' for all of the libs, instead of having an option for each
library. assuming that ffmpeg cant/wont encode files with different
encoders in the same run.

-vleo = video library encoding options
need -aleo too for faac/lame

could be a bad idea, i havent thought it out much.
