[Bf-cycles] OSL status update

[Thomas Dinges]

Hi,
work continues on the OSL backend.
Blender compiles with OSL 1.2, the inbuilt OSL shaders are updated 
mostly and it renders.

I updated the OSL docs: 
http://wiki.blender.org/index.php/User:DingTo/OpenShadingLanguage

They now contain step-by-step compile instruction for Linux x64.

Might be a good reference for other platforms as well. Anyone who would 
like to look into building OSL libs on Windows? :)

Regards,
Thomas
