Campbell Barton 5eaf9f90c1 BPython API 
added a function - GenericLib_assignData for assigning blender data, to assign an ipo to a camera or world to a scene for instance.
Using this function removed ~300 lines of code.
also fixes user count error in some places that didnt check.

also made it possible to clear the colorband by setting it to []
