Library manegement features:

- Outliner now shows hierarchy for Libraries, indicating which Library
  files invoked loading another.
- SHIFT+F1 "Append" browser has a Library menu, allowing to directly browse
  into all open library files. This will prevent accidents like re-opening
  a same .blend via another path.
