Outliner: brought back to near full functioning:

- proper operators, like for open/close items, exec operations
  (note: select is still same operator as activate, should
   become modal ops later)
- rename works again (ctrl+click)
- proper notifiers for redraws
- select / extend select works again
- editmode in/out works again
- enter key opens/closes again
- right mouse operations work again

Didn't do:
- options for Sequence strips
- signals to change button views on clicks
- error/warning messages

UI:

- added new uiButSetRenameFunc(), which passes on the old name
- added uiButActiveOnly(), which ensures a button gets created in
  active state, and gets removed when used. Needed for editing
  names in outliner.

  Andrea: check outliner.c for uiButActiveOnly(), very easy to use!

Also:

- Added posemode operator, CTRL+TAB tied to it.
