* Included FFmpeg library for video encoding. (LGPL, dynamically
linked.)
* Added 'record' button to cinematics - plays the selected track at a
fixed framerate, and saves the output to a video file (preferably
MPEG4). Slightly lacking in reliability and features (fixed at 640x480,
no choice of codec, probably crashes horribly if any problems occur
while encoding, etc).
* Moved icon bitmaps out of mods directory. Added 'record' icon.
This was SVN commit r4676.
