Some design changes to brush models to support
GL_ARB_vertex_buffer_object:
  - The vertices and texcoords no longer live in glpoly_t.
    (They now live in mod->brush->verts and mod->brush->tcoords)
  - mod->brush->vbo_objects, if we have VBO then this contains the
    VBO IDs for the 3 arrays. (Use the defines luke.)
  - Two new GL typedefs, note, I'm 99% sure that nVidia has them wrong,
    but we have to remain binary compatable with them.
  - We no longer subdivide polygons, tough shit. (See below.)
  - DISABLED BY DEFAULT: You must pass -vbo as an option to enable VBO
    support, this will be removed once I figure out which drivers
    really need a disable quirk.

A new effect for water drawing, no swirls or ripples, just moving.

Killed old skys, we now have sky spheres. (AKA sky domes.)
FIXME: Really slow, I don't know why yet.
