Sculpt Branch:

* Don't allow adding/removing multires levels in editmode.
* Customdata code for swapping mdisps restored.
* Fix inflate brush crashing with multires.
* Smooth and layer brush don't work yet with multires, but at
  least avoids crashing now.
* Fix threading issue with flatten brush.
