refac: Sidebar reorganized In order to make context switches between administrative tasks which are map related and those which are system related, we now have a category "administration" and "systemadministration". The Riverbedmorphology does nothing than display the map, so it is renamed to that (map). In case the context of "systemadministration" is chosen, the "map" brings you just back to the map.
