gl_draw.c: gl_lightmode now uses a callback.

gl_dyn_part.c:
  Now uses a (non-locked) vertex array to reduce GL calls.
  Gives a slight speed gain, I'll optimize it a bit more soon.
gl_rlight.c:
  Fixed much of the dlightframecount issues.
  (This gives cleaner code and a speed up.)
gl_rmain.c: A slight reorg of the dlight call order.
gl_rmisc.c: Enable some of the vertex arrays. (vertex, texcoord, color.)
gl_rsurf.c:
  Reworked R_BuildLightMap, smaller now code wise, also more optimized,
  and it builds a 0-2 lightmap in more cases now.

  Playing with GL_UploadLightmap.

  For non-lighthalf non-mtex lightmaps use a 0-2 range.
  (Makes gl_lightmode look a /lot/ better.)

gl_screen.c: More stuff with the gl_lightmode callback.
r_view.c: R_PushDlights is called elsewhere now.
sw_rmain.c:
  Moved the R_PushDlights call.
  Also killed the unused PASSAGES define.
