Todo items:

- Toobar views were reset on hide/unhide. Now they keep the view
  and zoom level.
- Added operator to delete all unused 'space data', this to make
  clean startup.blend files, remove unused editors, and to be
  able to test starting defaults for editors.
  No hotkey, use search for "Clean-up space-data"
