* fixes minor bug where invalid geometry (self intersecting) could not be used properly as input for WFS parcel intersection calculation
* future enhancements regarding map client will make sure invalid geometries can not be added in the first place
* 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 optional short_name rendering for selectable codes
* refactors autocomplete field for compensation state into custom js tree widget
* adds single select (radio) alternative to tree widget templates
* changes trigger for sending data to EGON: on each new payment, edited payment or deleted payment action, the data will be sent to EGON instead only once on "recording"
* refactors parcel table into a dynamic table, which does not show all content at once but rather supports pagination and a button which triggers loading of more content
* adds translation
* 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
* adds button and functionality for leaving a team
* if the admin leaves the team, another user will be chosen as new admin automatically
* improves Team (django) admin backend
* better control over user adding-removing
* only added team members are selectable as admin
* 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 in egon_export.py where missing payment date would result in non writing of gml
* fixes bug in egon_export.py which occured due to extension of parcel data fetching
* updates unavailable.html report content, such that users will understand why a recorded entry might not be visible, yet
