3D Texturing: Undo.

Blender can only support a single undo system per undo step. As sculpting/vertex colors are mutual exclusive operations
out approach is just to switch the undo system when painting on an image.

PBVHNodes contain a list of areas that needs to be pushed to the undo system.

Currently the undo code is in sculpt_paint_image. We should eventually support undo for color filtering and other nodes.
we might need to place it to its own compile unit so more brushes can invoke the same code.
