[quake3] Quake 3 Raytracing Patch

You know, the fact that the source code for Daniel Pohl's project is still 
not available after all these years was one of the reasons why I considered 
donating my work to the ioquake3 project. I simply hope that some people 
pick it up and continue development because there's still so much to do, 
more than a single person can handle! I don't want my diploma thesis to just 
leave some screenshots and a long text behind. I want it to have a future 
and I want it to be useful for others, who might be interested in learning 
this stuff.

I was also working on a "level viewer" like Daniel Pohl (see 
http://www.youtube.com/watch?v=F31kVvyx1Fw), but that can hardly be 
considered a game. It's more useful for benchmarking of raw ray tracing 
performance Now, ioquake3 on the other hand can be used to assess the 
quality of a raytracer when it comes to real world gaming environments.
