* Renamed some files to try and start cleaning up the project... Next on the list: Move all irrelevant stuff out of Renderer. Fix naming conventions for all managers/handlers/"systems".

* Halved size of marching cubes chunks. Visually there's no difference, but I want to start implementing some form of collision detection against the mesh, and that's when I want smaller meshes.

* Optimized geom shader grass for better performance. It now  discards faster if it's too far away. Also doesn't apply wind forces unless grass is close enough.

* Changed ordering for toggling SSAO, also enabled SSAO again. You can toggle it on by pressing 6 once.

* Changed point light specular algorithm back to phong. Used to be some half-assed blinn-phong that didn't work so well.
