Switched to using index vertex arrays
Refactored buffers class to handle different types of arrays
Turned on antialiasing
Central config for experiments
Some different experiments in rendering methods
 - test1.py - instanced, model data as vec4 attribute
 - test2.py - uniforms, looping in python as a reference. 20x slower
 - test3.py - instanced, models are full matices
     - not fully working
     - probably not worth it
     - keeping arround cos it shows how to do mat4 attributes
