Log Message:
-----------
Constraints API: ID-Loopers
Added a system for running a callback on all the ID-blocks referenced by constraints (like for modifiers). Also, added an API function which calls these on the constraints present in the given list.
These could be used for:
- the proxies + action/pyconstraint fix that campbell committed
- simplification of file loading code
