* Compile all of cycles with -ffast-math again
* Add scons compilation of cuda binaries, tested on mac/linux.
* Add UI option for supported/experimental features, to make it
more clear what is supported, opencl/subdivision is experimental.
* Remove cycles xml exporter, was just for testing.
This change adds RNA access to tesselated face UVs and colors (MTFACE and MCOL), primarily for use by plugin renderers (e.g. cycles). The RNA mesh properties to get to these are prefixed with "tessface_" and additionally the help text states that these are for renderers, to try not to confuse existing mesh editing tool scripts into thinking they could just start using these values.

Rationale: the name was confusing and not always used consistently, and this
map itself is not something that can be layered, rather the map can be used
as texture coordinates in some layered setup.
The original intent was to indicate this contained more than just UV's, but
the game engine settings have already been moved out, and apparently users
didn't really get this from the name anyway.
Regarding merge status, there should be no build failures, but cycles may not
be enabled in your build, we are still solving:
* Windows: CUDA kernel compile at runtime is failing, probably will have to
do precompiled kernel again.
* Mac: scons is not building cycles yet.
* Linux doesn't have boost + openimageio libs available in lib/ yet, so it
requires manual install of those libs still.
* Fix missing update when editing objects with emission materials.
* Fix preview pass rendering set to 1 not showing full resolution.
* Fix CUDA runtime compiling failing due to missing cache directory.
* Use settings from first render layer for visibility and material override.
And a bunch of incomplete and still disabled code mostly related to closure
sampling.
