Blender modifications for Cycles integration.

Browse Source 
Some notes about code status:

* The Blender modifications were fairly quickly put together, much more code
  polish and work is needed to get this to a state where it can be committed
  to trunk. Files created with this version may not work in future versions.

* Only simple path tracing is supported currently, but we intend to provide
  finer control, and more options where it makes sense.

* For GPU rendering, only CUDA works currently. The intention is to have the
  same kernel code compile for C++/OpenCL/CUDA, some more work is needed to
  get OpenCL functional.

* There are two shading backends: GPU compatible and Open Shading Language.
  Unfortunately, OSL only runs on the CPU currently, getting this to run on
  the GPU would be a major undertaking, and is unlikely to be supported soon.
  Additionally, it's not possible yet to write custom OSL shaders.

* There is some code for adaptive subdivision and displacement, but it's far
  from finished. The intention is to eventually have a nice unified bump and
  displacement system.

* The code currently has a number of fairly heavy dependencies: Boost,
  OpenImageIO, GLEW, GLUT, and optionally OSL, Partio. This makes it difficult
  to compile, we'll try to eliminate some, it may take a while before it
  becomes easy to compile this.
