I modified the outliner so that a more file-browser behaviour is now present:

Changed (to fit "normal" behaviour of trees):
a) ctrl-left-click now let the user select single objects It's like the normal behaviour in e.g. file browsers. [was before: shift-left-click]

b) added new menu entry on right-click "rename". [was before: ctrl-left-click]


NEW:
c) shift-left-click now lets the user select multiple objects at once (e.g. like in every normal file browser). [was before: not available]
