Vega Strike Code

Added .blend files for gleaner, diligence and franklin, and updated blend file of the Knight.

Added .blend versions of .bfxm's for Anaxidamus and Robin, for future work.

Ticket #38 mostly done: Integration of SUCSS for streaming of movie audio.

Issues remaining:
* Long hiccups in the event loop make the streaming source stop playing. It won't resume automatically - which is bad.
* Long streaming buffers create lipsync issues, even with OpenAL's supposedly accurate playing time. Add the previous point (which requires long buffers to avoid streaming to halt), and we're in trouble.
* Code a GUI.py abstraction for playing videos in full screen... so it's mod-friendly (right now, everything's too low level). Mostly the interaction with the Music DJ, which is complex.

The first two issues would be easily solved by threading the streaming part of the renderer... will have to look into that.

Bugfix: negative seek times would bring all sorts of crashy trouble.
Although negative seeks are wrong, crashy trouble is... wronger.

Bugfix: lin_time's queryTime() wasn't doing what I thought it did.
Implemented lin_time's realTime(), which does what we want.

Fixed ffmpeg/swscale detection issues.

Fix nasty buffer underflow in vsfilesystem.cpp

Bugfix: playtime query on streaming sources was broken:
OpenAL only reports the current buffer's play time, so in order to get accurate time stamps,
we must add the current buffer's start time to the reported time.

Now the tests report 27ms maximum drift: ain't that great?

move ffmpeg module specific advance flags back to ffmpeg module, GTK2 still needs this done too

Merging fix from safemode branch -r12759, forgot to cache a few variables
