This patch will add dedicated ContextMenus for constraints/modifiers in the outliner (the formely used 'data operations' didnt make sense and were not implemented anyways)
atm. constraints will have a context menu with following entries:
- enable
- disable
- delete
and. modifiers will have a context menu with following entries:
- toggle render
- toggle viewport
- delete
I remember seeing a couple of reports mentioning that stuff from the ContextMenus is not implemented or just not doing anything at all, so this should also take care of those reports (at least for constraints/modifiers now)...
(this is part of more work on the outliner, I've split this up in smaller pieces for review now...)
Let me know what you think...
