assrender plugin (ASS/SSA renderer via libass)

assrender plugin that works much like textoverlay. It has two sink pads:
"video_sink" and "text_sink". Receives RGB24 video frames on video_sink and raw
(i.e. unparsed) ass events on text_sink. Overlays subtitles directly onto the
video.

Features:
* ASS/SSA parsing and rendering via libass
(http://sourceforge.net/projects/libass/)
* on-the-fly registering of fonts that are attached to the stream. This
currently only works with fonts attached to matroska containers using the
latest CVS version of the matroskademux plugin.

Limitations:
* only RGB colorspace is supported. Needs colorspace conversion for YUV video
frames.
