Outliner options;

- Added in pulldown the current view commands, including the 'show
hierachy' option, which shows only the full object tree
- You now can activate data by clicking on the hidden icons (displayed in
a row of a collapsed item)
- Added selection and display of active NLA strips
- Cleanup; white text in outliner only for active object
- Made hierachy helplines 1 pixel wide and black, looks nicer
