Brecht Van Lommel 66b1dfae89 Cycles: tweaks to properties and nodes
* Passes renamed to samples
* Camera lens radius renamed to aperature size/blades/rotation
* Glass and fresnel nodes input is now index of refraction
* Glossy and velvet fresnel socket removed
* Mix/add closure node renamed to mix/add shader node
* Blend weight node added for shader mixing weights

There is some version patching code for reading existing files, but it's not
perfect, so shaders may work a bit different.

alternatives?
- use a single big 1D texture, and do our own lookup/filtering
- group by size and use a 3d texture, performance impact
- group into larger texture with some padding for correct lerp
also note that cuda has 128 textures limit, we use 100 now, since
