Attached is a patch that adds the new actions and changes the action bar configuration for deletion.

There is however a problem with it that i have not been able to solve yet. When restoring a previous version it fails with StaleItemStateException.

• The second attempt however always works.
• It also works when the node (user, group or role) does not have any child nodes.
• It also works if you delete a folder with a user inside it.
