Merge setting weapon shader color into missionpack ui
Missionpack uses q3 models in all non-team gametypes
Specify lightmap and vertex as hight and low in q3_ui

Fix setting display height and width in glconfig

Display height and width were getting cleared at video restart.
Fallback height and width were swapped.
Add display video mode (r_mode -2) to q3_ui settings
Use r_customheight/width to get r_mode -1 size

glconfig should work, but this makes it clearer getting info from r_customheight and r_customwidth. Plus have to set r_custom* vars, so it's not like it removes usage in mod code.
Label this ifdef like the rest of it's kind
