Integrating Sunflow

I've been playing around with some utilities for moving lights around a scene and rendering it in Sunflow for years.  I've done so much rewriting just to destroy it over and over again, I decided to just take much smaller bites and try doing something very tiny with the program.

• import a PLY object (buggy)
• add an attentuated spotlight
• camera controls (incomplete)
• adjust basic global illumination
