[evolution-kolab] EPlugin: new default selection for the ACL "edit" sub-dialog

[Christian Hilberg <chilberg src gnome org>]

commit bed56dc845c8f13a45aebda7d06de79418705b46

    EPlugin: new default selection for the ACL "edit" sub-dialog
    
    * added a "Keep the current permission settings" radio button
      to the group, so that we can activate the sub-dialog "OK"
      button once there is a change to the selection in the
      ACL settings radio button group (needed since this button
      group is the only initially sensitive widget in that dialog
      other than the "Cancel" button)
