Quality of Life improvements

* disables ordering of parcel_group ("Gemarkung") column on tables
    * ordering can not be done properly due to more complex nature of this column's content
* introduces "Keine Geometrie vorhanden" message instead of hour glass icon on entries where no geometry has been entered yet
* properly orders last_modified column by moving null values to the lower end of the ordering
