#146 Admins and update_all_parcels.py

* extends admin backend
    * adds found_in_codelists to KonovaCodeAdmin to see where a KonovaCode can be found in
    * improves rendering of after_states and before_states for all AbstractCompensationAdmins
    * adds geometry_id to all major datatype admin backends
    * adds st_area like calculation to geometry admin backend
* update_all_parcels
    * orders geometries by size (small to big) to process smaller geometries first and bigger later
    * adds more output to command for a better overview of what is just going on
