- Moved the spatial tree stuff into it's own component type, and have the light + renderable derive from it.
- Lighting visitor implemented, basic implementation (it won't cache, and it won't even lerp) in and working, but it of course will need some improvement later on.
- OBJ loader generates normals and tangents.
- Added static mesh shader permutation.
Added base dist folder to engine for reference, and so we can keep all core shaders under source control.
