Disconnect/connect hair:
- Moves hair from face-space to global space and back.
- Allows for editing of emitter mesh after hair combing.
- Disconnect hair before doing topology changing changes in mesh edit mode, connect after changes.
- Notes:
* The closest location on emitter surface to the hair root is used to connect the hair.
* Emitter deflection, sticky roots and add brush don't apply for disconnect hair in particle mode.
- Todo for future:
* Copy disconnected hair from object to another (when 2.5 has proper copy operators again).
* Possible automatic disconnect/connect with topology changing operations in mesh edit mode.
Other changes/fixes:
- Proper subtypes for some particle mode notifiers.
- Particle mode selections didn't draw correctly because of using lighting for the paths.
