Audio

lilliput now supports Audio. Also, enable -fPIC in builds for greater compatibility.

Fixes for outstanding bugs

This change forces lilliput's output to never exceed 8 bits per channel, which isn't supported by many image containers. Also, it includes some tweaks to the libavcodec wrapper to support more videos.
