- move: material.add_texture(tex, coords, mapto) --> material.texture_slots.add()
- added material.texture_slots.create(index), material.texture_slots.clear(index)
- texture slot functions also work for lamp and world now.
Other minor changes
- allow rna functions to set FUNC_NO_SELF and FUNC_USE_SELF_ID at once.
- [#23317] Changed some operators' RNA to accept lengths, a modification I made to this patch made it not work as intended, removed this edit so unit buttons appier in the UI for certain operators.
- Sphinx doc gen, 2 columns rather then 3, didnt quite fit in some cases.
Thanks to example .3ds file and bug report from stridernzl.
1) The API function for adding textures to meshes was not working correctly, resulting in a Null texture slot being created (i.e. a texture slot was created, but the given texture could never be assigned to this).
Fixed by making the function always require a texture as input (as with other places that use pointers as arguments).
2) In "Textured" draw mode, the imported meshes were shown white (i.e. without any textures).
It appears that that the old old setting (mesh.faceUV) is no longer valid/wrapped in RNA, so worked around this by setting the 'tex' setting for UV-faces on. From the UI, this seems to do the same thing as entering editmode and assigning an image to the faces from the image editor.

I've also removed a few lines of commented 2.4x code that is no longer valid. Hopefully there wasn't anything too valuable that I accidentally removed in this process ;)
