V17 of VBO/GLSL patch

v17.

Just a maintenance update really, to make sure the patch applies cleanly still.

Still, there are some useful features and fixes:

- close shadow casters are merged into the same shadow, which should have some
performance benefits.
- a bug where shadows would show up on the wrong side of a surface was fixed.
- a nasty bug with rendering portals was fixed, where the zFar value wasn't
reset.
- the lightmap value is modified in the glsl shader when a deluxe map is used,
since lightmaps are diffuse shaded.
- the shader keyword "specularReflectance" has been added, for use in the
"stage specular" stage.  This is basically a crossfade between diffuse+fresnel
lighting at 0, and purely specular lighting at 1.  If not specified, the patch
defaults to 0.04.
