* 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)
* fixes InterventionAutocomplete bug, where team-shared entries would not pop up as valid option
* fixes bug where form opening for new compensation without direct intervention link resulted in 404
* adds intervention-recorded check on deduction forms: Form is invalid if intervention is currently recorded and therefore blocked for any editing
* extends basic check_for_recorded_instance() method to let some forms pass, e.g. deduction related forms on ecoaccounts which only have a reason to be rendered IF the entry is recorded
* adds/updates translations
* adds new modal form content template recorded_no_edit.html
* adds modal content change, such that no data can be edited on any form as long as the entry is recorded -> instead, users are informed on the form, that the recording state prohibits editing
* adds translations
* 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
* fixes bug where created timestamp has been displayed on modified attribute on detail views
* enhances localized date and datetime rendering
* reorders sub menus in user's profile hub
* 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
* adds tests for team sharing
* extends the API for team sharing support
* adds shared_teams property shortcut for ShareableObjectMixin
* adds full support for team-based sharing to all views and functions
* simplifies ShareModalForm
* adds/updates translations
* adds team sharing field to share form
* splits sharing logic into user based and teams based
* adds TeamAdmin for admin backend
* adds validity check on Team name -> only unused names shall be valid
* changes action_type from ForeignKey into M2M
* adds migration
* changes form widget
* WIP: changes rendering on detail view of compensation
* TEST NOT CHECKED YET!
* 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)
* adds parcel district column for all major data objects
* adds warning about intervention-revocation on index view of compensations
* adds warning about intervention-revocation on detail view of related compensations
