Cycles: glossy and anisotropic BSDF changes

Browse Source 
* Anisotropic BSDF now supports GGX and Beckmann distributions, Ward has been
  removed because other distributions are superior.
* GGX is now the default distribution for all glossy and anisotropic nodes,
  since it looks good, has low noise and is fast to evaluate.
* Ashikhmin-Shirley is now available in the Glossy BSDF.
