Apricot Branch: material GLSL shaders

=====================================

- Currently only supports node-based materials, with some nodes,
  main purpose of this commit is to get the infrastructure in
  place, more material options will be added in the following weeks.
- Supported shader nodes: camera, curves, geometry (everything
  except global and front/back), curves (partially), huesatval,
  invert, mapping, math, mix/add/mult/sub/div, math, vector math,
  normal, output, rgb, separate/combine rgb, squeeze, basic image
  textures, value and output.
- Lights and shaders are still missing, but since the SoC project
  had these working quite far it should be possible to reuse that
  code.

- Enable using "GL Shaded Mode" in the user preferences. It will
  replace regular shaded mode with glsl shaders.
- If the material is not node based or has an error in it, it will
  revert to solid shading. Need to do this kind of error handling
  better and make it posssible to still run even with some
  functionality not supported.
- Integration with texture loading in textured mode is very poor,
  needs to be revised.

- Only added support for Scons and Makefiles.
- Added GLEW in extern/. There were some conflicts with the game
  engine opengl extensions but managed to solve them. Still, it
  would be good to use single mechanism for opengl extensions.
- Added a "gpu" module in source/blender. It has quite a lot of
  code with much of it uncommented as well, some of that will
  become used and some it will be removed later.
- OpenGL shader code is currently converted to a C file with
  datatoc (which now 0-terminates the arrays), but this has to
  be done manually still, need to figure out a better way or
  integrate it into the build systems.
