Started converting things over to assimp...
Rudimentary model drawing through assimp
Textureless model rendering
Added textures support. Still kind of flaky, needs to be optimized.
Memory management changes, checking if scene loading failed. Modified
gitignore for additional model.
Added some more assimp import flags
