Version 5 of VBO and GLSL code from xreal, w/ changes

I've changed a few things again.

This version of the patch removes the occlusion stuff I had in the previous
patch, and adds GPU vertex skinning from ET-XreaL, as well as optimized
vertex/fragment programs and some fixes here and there.

It's actually reasonably fast now, with s_useOpenAL set to 0 it's faster than
base quake3.exe.  It's still slower than ioquake3 1.36, though.

With "timedemo 1;demo four" I get:

quake3.exe:
1260 frames, 4.3 seconds: 296.2 fps

ioquake3.exe SVN with VBO/GLSL patch:
1260 frames 3.7 seconds 342.9 fps 1.0/2.9/9.0/1.0 ms

ioquake3.exe 1.36 from website:
1260 frames 3.4 seconds 373.4 fps 1.0/2.7/6.0/0.9 ms

So there's some room for improvement. :)
