Cycles: add location/rotate/scale and XYZ mapping options for all texture nodes,

to reduce the amount of nodes needed to set up a simple texture.

These are currently editable in the texture properties tab, still need to make
them available in the node editor. Projection and color modification options will
be added later, they're not implemented yet but allocated already to avoid
version patches later.

Also an issue with the XYZ mapping is that when you set one to None, texture and
material draw mode doesn't draw the image texture well, OpenGL doesn't seem to
like the degenerate texture matrix?
