Eesho's patch for new noise textures!

Basically this provides three new things:

1. Choice of a list of noise-base functions, which can be used by the
   current Clouds, Marble, Wood textures as well.
2. Three new texture types: Musgrave, Voronoi and DistortedNoise
3. Python access to noise functions (not for render!)

All of this together makes Blender's builtin procedural textures a LOT
more powerful. Here again, a full webpage should be made to show off all
possibilities, and explain some of the more scientific names for settings.

A good read on Musgrave textures can be found here:

About Voronoi:

I can't find official DistortedNoise docs easily... maybe its something
Eeshlo created himself.

I've spent some time to change the patch Eeshlo provided. Worth noting:
- created main texture "Musgrave" with 5 sub choices (instead of 5 new
  main textures)
- added for all new textures the option to scale (zoom in out)
- added patch in do_versions to initialize variables

I hope the Python team will check on the Noise.c API. And include in docs!
