Brecht Van Lommel 22f05adc3a RNA 
* The RNA viewer is now more integrated with the outliner, as
  a "Datablocks" view, with a tree structure.
* Still some issues to be solved with persistence, and also
  memory usage is problematic when expanding a million vertices
  in a mesh for example, though it will not build closed parts
  of the tree.
