fteqw/engine/qclib/execloop.h
Spoike 6e3f69f504 d3d rendering is diabled (framestate, read later - merged will compile just sw+gl for now). 
fte particle scripts are disabled (classic works).
I'll fix these in the new year.
Redid framestate stuff again. Slightly better now, but this is the bulk of the changes here.
Reworked the renderqueue to provide batches of items instead of individual items. This cleans up the particle rendering code significantly, and is a step towards multiple concurrent particle systems. fte's scripted particles are broken as I'm trying to find a way to rework them to batch types together, rather than having to restart each batch after each particle when you have two particles in a trail. I'll fix it some time.
Reworked some alias model code regarding skeletal models. Added some conceptual skeletal bone control builtins available to csqc. Currently it can query the bone names and save off animation states, but can't animate - its just not complete.
Added more info to glsl custom shaders.
Updated surface sorting on halflife maps to properly cope with alphaed entities, rather than just texture-based blends (q2-style).

//qc execution code.
//we have two conditions.
//one allows us to debug and trace through our code, the other doesn't.
//hopefully, the compiler will do a great job at optimising this code for us, where required.
//if it dosn't, then bum.
//the general overhead should be reduced significantly, and I would be supprised if it did run slower.
//run away loops are checked for ONLY on gotos and function calls. This might give a poorer check, but it will run faster overall.
//Appears to work fine.
