only user of 'loadmodel' outside of gl_model.c was Sky_LoadTexture,
so changed it to accept a model pointer.
TODO: remove need for globals such as mod_base, loadmodel, loadname
md3 support
quoth/etc bug fix
strzone bug fix
png/jpg replacement wall textures
rewrote mdl rendering to always use arrays, relaxing vertex+tri limits.
removed static ents limit
fixed ambient_level not working at high framerates.
This raises LMBLOCK_WIDTH/HEIGHT from 128 to 256 which should
be supported everywhere and decrease draw calls

This is for emulating a low-resolution pixellated look,
or possibly as a performance boost on slow graphics cards.

Prevents console spam on "developer 1" if a mod calls PF_VarString often (e.g. In the Shadows textbooks).

MAX_MAP_LEAFS: 65535 -> 70000
MAX_LIGHTMAPS: 256 -> 512
TODO: maybe drop static arrays based on MAX_MAP_LEAFS like, see R_InitVisCache in RMQEngine.
TODO: dynamically allocate the static `lightmaps` array as well; with this last limit increase it's 32MB.

Fixes bug where the fog mode was resetting to the default (GL_EXP) after a mode switch, causing fog to look different. This was only affecting SDL1 for me.

Initially I thought that we would never need to draw an alias model that hadn't been precached when R_NewMap runs, but this assumption turned out to be incorrect. This fixes the issue where progs/bolt.mdl wasn't rendering in the Scourge Done Slick demos.

new worldspawn keys: _wateralpha, _lavaalpha, _slimealpha, _telealpha, _skyfog (unique to Quakespasm)
The lava/slime/telealpha cvars are non-archived, and default to 0, which means to use the value of r_wateralpha, so they have no effect by default.
The worldspawn keys allow custom maps to set these values in a way that only applies while the map is loaded, and doesn't change the cvar value. (similar to the behaviour of the "fog" worldspawn key.) They are accepted with or without the underscore, like "fog".

Avoids general bugginess of hardware gamma, doesn't affect the whole screen in windowed mode like HW gamma. Should fix http://sourceforge.net/p/quakespasm/bugs/5/

In GL_MakeAliasModelDisplayLists, after saving the standerd triangle strips and fans onto the hunk, if the system is GL2 capable, we also save a second version of the mdl on the hunk designed to be loaded into a VBO (GL_MakeAliasModelDisplayLists_VBO). In R_NewMap, and on video mode changes, we call GLMesh_LoadVertexBuffers which loops over all precached mdl's and loads the data into a pair of VBO's (vertices and vertex indices).
Finally, in R_DrawAliasModel, assuming no rendering options are disabling the fast-path (r_drawflat 1, r_lightmap 1, or r_fullbright 1 would disable it), we call GL_DrawAliasFrame_GLSL, which sets up all of the bindings and draws the (possibly lerped) mdl in one glDrawElements call.
Special thanks to MH for some of the code from RMQEngine and the general concept.

R_DrawTextureChains_Multitexture: revert to the way it was before VBO support was added.
gl_texmgr: expose GL_SelectTexture. make the implementation less convoluted and support 3 TMUs.
gl_vidsdl: check GL_MAX_TEXTURE_UNITS
r_brush: only create VBOs if 3 TMUs available

This seems to help fps a fair bit on maps with a lot of world polys like jam2_tronyn. Tried on a few computers with intel and nvidia gpus, windows, mac os, linux, and there's always at least some fps improvement. Best case was 70fps -> 96fps on jam2_tronyn, on OS X + nvidia 650gt.
Interested to hear how this works for amd gpu's, just do a timedemo with and without "-novbo".
Only downside is I had to disable the fast path in Vid_Toggle_f() because at least with SDL1, the vbo no longer works after a toggle. So as a result, fullscreen toggles with alt-enter are slightly slower.
