When an access right is clicked on, load the content of the right into the "add right" form. This allows a user to edit the contents and click add. Depending on the type of the modification, the right will either be added, or if appropriate, it will replace the old right. Also factor out the "add right" panel into a new class: AccessRightEditor. Refactor and clarify much of the operation of this class. Bug: issue 558 Change-Id: Ifbcf3100a2a629a5b8774b03c436ca0b7e5995d4
