UI:

* Added Constraints template and Add Constraint operator.
* Added toggle=True/False parameter to uiItemR, to get a
  toggle button (actual button) rather than an "option"
  button (checkbox) 
* Added OPTION/OPTIONN button type, to distinguish with
  TOG/TOGN.

RNA:
* Make all modifier pointers editable, including correct updates.
* Added notifiers and updates to constraints.
* Fix a stack corruption, pointed out by Andrea, and potentially
  causing crashes.
