FFusion

This is a revival of the old FFusion QuickTime component, updated through the Perian project and extracted from there by RJVB.
It aims to be a decode-only codec leveraging FFmpeg to do the actual work.

For now it is based on libavcodec v52, as is Perian; the goal is to port it to use the current libavcodec, and then
to build it for win32 QuickTime. In hope it'll improve playback performance for mp4, h264, etc. files.

The source is hosted on GitHub, the SourceForge project holds the resulting and required binaries.
