ioRTCW-PS3 changelog

This one took a while. Most of these are from Mayo1970's ioQuake3-PS3 port. https://github.com/Mayo1970/IoQuake3-PS3

Performance
-vertex work on the RSX: a new vertex program computes every shader stage's colors, texture coordinates (environment maps, tcMods), the lighting of characters and models, and the wave / bulge / move deforms on the GPU, instead of the PPU going through every vertex of every stage. GL fog is drawn by it too.
-the later stages of a surface reuse the first stage's copy of its vertices and indices.
-r_ps3_vprog 0 in the console goes back to 1.0's way, for comparing or if something draws wrong.
-the crosshair picker in Options (and in the in-game options) now works with the pad: select it and press Cross or left / right.
