- Bug fixes for radio render (yes, releasing gives more reports!)

1. Rendering with material without radio flag sometimes caused scanline
   errors. The 'rad' value for rendercore loop wasn't reset in all cases
2. The color didn't truely match the color when using 'radio tool'.
   Cleaned up a few old lines in rendercore loop... accidentally one
   calculation was done double.
3. When adding new radiosity block, 'max iterations' is set at 120. this
   prevents noobies/experiment from going into radio-solving with a long
   itteration time (it exits at convergence < 0.1)
