Messy commit - moving to SDL 2 and/or getting rid of SDL for boost and straight openGL
Put shaders and some very basic OpenGL stuff in, took out SDL, added in new libs. Committing before I mess something up.
Before I mess anything up too badly, messing around heavily in Input Handling
Input sytstem is coming along, need to hook up a script/callback manager now to make sense of input mappings
Added the base level of a script manager - will be hooking up some kind of handle->callback functionality at the very least, later will add lua bindings. All this to hook up input, sheesh
