Adds support for frameserver rendering to blender. This is done by integrating a mini-webserver (around 300 lines of code) into blender. Using the VFAPI-plugin in contrib/windows it enables blender to directly feed its output into TMPGEnc, a commercial high quality MPEG-Encoder. Since it is a mini-webserver, you can probably easily use it for other interfacing purposes.

this patch features several cleanups and bugfixes for the sequencer: - blur works again (this was a serious bug in gamwarp...) - seperates all sequence effects into a seperate file with a clean interface - thereby fixing some obscure segfaults - seperates the scope views into a seperate file - adds float support to all effects and scope views - removes a bad level call to open_plugin_seq - FFMPEG seeking improved a lot. - FFMPEG compiles with debian sarge version cleanly - Makes hdaudio seek and resample code really work
