Texturing: texture and 3d view draw type changes, these should only have any

effect for a render engine using new shading nodes. In short:

* No longer uses images assigned to faces in the uv layer, rather the active
  image texture node is what is edited/painted/drawn.
* Textured draw type now shows the active image texture node, with solid
  lighting.
* Material draw mode shows GLSL shader of a simplified material node tree,
  using solid lighting.
* Textures for modifiers, brushes, etc, are now available from a dropdown in
  the texture tab in the properties editor. These do not use new shading nodes
  yet.
