Log Message:
-----------
Tomato Cycles:
* Added a Brick Texture Node to Cycles.
* Based on the Blender Internal Brick Texture with some modifications.
* Tested on CPU and GPU (CUDA & OpenCL)
Documentation: http://wiki.blender.org/index.php/User:DingTo/CyclesBrickTexture
ToDo: Only works correct on flat surfaces, like a Plane. If you attach the
shader to 3D objects like a cube, the mapping is not correct on the Y/Z vector.
Thanks to Lukas Toenne for fixing a issue I had with the Node code! :)
