revised shaders to actually do alright shading. does a barrel roll
added subcomponent transforms to graphics components, so you can now add models to other models
fixed a bug with passive subcomponents not updating, added a passive subcomponent to the test. It's definitely not a top hat. There will be no top hats in Awesome-Kart
added a wheel model, it's not on quite right, but it's good enough for now, this guy is almost totally ready to present
