Spoike 9cd988a836 Added csqc->ssqc requests. 
Fixed up cl_indepphysics. Sending is fully independent, bar sync points.
Fixed so #if 0 works in qc code.
Fixed up error conditions in qclib when features are not supported.
The webpage generator will now refcount properly.
Fixed error conditions when using glsl shaders.
If MULTITHREAD is defined, r_loadlit will not light inside a separate thread.
We now generate VBOs for bsp objects. Shaders/rtlights don't use them yet.
Fixed up MVD/multiview playback a bit. It now looks like it works! (cl_hightrack will no longer track the same person in all views).
Fixed error conditions when attempting to download versioned csprogs.
Reduced the number of places that a q3-style marked up string is expanded. I think there are a couple places left still though. Approximated ezquake colour codes.
Memory mapped read file access in win32, where we can. Not sure about this. Lets see how things pan out.
