Changes since: https://issues.apache.org/jira/browse/HARMONY-5912
-Bugfix of the following: if we edit a policy entry, edit one of its principals, we click ok, then we click cancel on the policy entry dialog,
then the changes made on the principal dialog will be permanent.
Solution: A working copy is used for both principals and permissions until we click ok on the policy entry dialog.
-New dialog: PermissionEditFormDialog to view and edit the permissions of the grant entries.
The available permissions, their target names and the actions are pre-loaded in combo boxes.
Ok button of the permission edit dialog is not yet handled to add the constructed new permission.
