* drops identifier handling on all edit-forms (identifier editing has been disabled on the frontend for a while now)
* updates test cases
* updates form caption for checking and recording action (less intimidating)
* optimizes district column width
* fixes bug on frontend parcel fetching on detail view
* adds extended tooltip for title column on index tables
* retraslates 'Law' to 'Rechtsgrundlage'
* adds another validity check to SimpleGeomForm (is_size_valid) to make sure the area of the entered geometry is somehow rational (>= 1m²)
* optimizes performance of django command sanitize_db
* extends Geometry model with two new attributes, holding timestamps when a parcel calculation has been started and ended
* finally drops unused update_parcel_wfs in favor of update_parcels in Geometry model
* refactors update_parcel method
* adds geometry buffer fallback in schneider/fetcher.py to avoid emptying of geometries when parcels shall be fetched
* finally removes utils/wfs/spatial.py
* extends GeomParcelsView according to #381
* updates translations
* removes redundant psycopg2-binary requirement
* refactors update_parcels() method in Geometry model to work on Schneider
* old WFS based logic still exists as update_parcels_wfs() in Geometry model to have a fallback. Can be deleted in the future
* fixes race condition on geometry conflict calculation if performed in background process
* simplifies access to smaller buffered geometry
* adds mapping of "qm"->"m2" for UnitChoice in API usage for backwards compatibility
* fixes bug where holes in stored geometries would not be rendered properly on initial loading the map client
* drawback: multiple polygons are treated as a single feature on the map client. Not a real issue but maybe we can find a better solution to this
* quality of life: renders geometry area in m² on detail and report view
* adds number of all underlying parcels into parcel table
* reworks minor code parts of parcel related logic
* fixes bug where under certain circumstances a parcel would have been added twice to a geometry
* removes unused parcel fetching on intervention detail view
* adds geometry validity checks for SimpleGeomForm is_valid()
* shows validity problems on the form if a feature is invalid
* optimizes merging of different features into one MultiPolygon
* further enhances tests
* adds as_feature_collection() method on Geometry model for converting geom MultiPolygon attribute into FeatureCollection json holding each polygon as an own feature -> makes each polygon selectable in new netgis map client
* adds geom back writing to form field in case of invalid geometry, so the invalid geometry will be shown again
* updates tests
* fixes bug where race condition of celery workers could lead to duplicates in parcels (needs migration)
* 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
* improves frontend layout to display more details on district, municipal and parce group
* improves ordering of parcels
* refactors parcel related models
* improves parcel fetching
* extends and simplifies sanitize_db parcel related code
* improves the way parcel-geometry relations are stored on the DB
* instead of a numerical sequence we switched to UUID, so no sequence will run out at anytime (new model: ParcelIntersection)
* instead of dropping all M2M relations between parcel and geometry on each calculation, we keep the ones that still exist, drop the ones that do not exist and add new ones (if new ones exist)
* refactors table filters by introducing AbstractTableFilter, GeoReferencedTableFilterMixin, ShareableTableFilterMixin and RecordableTableFilterMixin
* adds full filter functionality
* refactors TableFilter inheritances for all objects
* adds rendering for detail view
* adds new includable html snippet for parcel rendering
* refactors generic includables in konova/ app into konova/templates/includes/...
* fixes bug where parcels have been reused from the database due to wrong model structure
* adds get_underlying_parcels() for Geometry model
* adds get_underlying_parcels() for GeoReferencedMixin models
* fixes bug where missing geometry would lead to an error during geometry conflict check
* removes unused wfs attribute from AbstractWFSFetcher
* adds/updates translations
* fixes bug in GeometryConflict conflict checking
* WIP: introduces new konova/utils/wfs/spatial holding SpatialWFSFetcher, which can be fed any geometry and it returns found features
* WIP: adds tests for wfs fetching
* updates requirements.txt
* removes unused messages
* adds geometry conflict message rendering for KOM and OEK
* removes unused methods in GeoReferencedMixin
* generalizes geometrical lookup for conflicts from overlaps to intersects
* refactors geometry field into GeoReferencedMixin, holding more handy methods and used in all models, formerly holding the geometry field
* refactors backend admin configuration, so modified, deleted and created are not editable in the backend which also skips loading of all possible choices
* fixes typo in sanitize_db command
* introduces GeometryConflict model, holding a link between two geometries, where one overlaps the other
* adds first (WIP) messages into detail views of ema and intervention for test purposes
