Version 2.0.0

Version 2.0.0 source is released as beta!

Here's what works:
Camera is fully adjustable for focal length, position, and view direction.
CSG Primitives started, Union only for now.
Sphere primitive.
Realistic matte lighting (no specular) with distance variation.
Multiple light sources part of CSG tree.
Point source light primitive works, parallel ray source planned.

What's up next:
Specular reflections
Parallel ray light source
Transparency / Refraction
More advanced primitives (image map / bump map)

That's all for now.
