Spoike 2937f9d861 Now understands spams setangles. 
D3D is a little more complete, lighting on models appears correct.
Added rate scaling to the sound system. Not sure on the configuration yet, and its not queryable in any way. Misc sound related cleanups.

//a note about dedicated servers:
//In the server-side gamecode, a couple of q1 extensions require knowing something about models.
//So we load models serverside, if required.
//things we need:
//tag/bone names and indexes so we can have reasonable modding with tags. :)
//tag/bone positions so we can shoot from the actual gun or other funky stuff
//vertex positions so we can trace against the mesh rather than the bbox.
//we use the gl renderer's model code because it supports more sorts of models than the sw renderer. Sad but true.
