* 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 support for payment adding/deleting to intervention log
* adds support for deduction adding/deleting to intervention/ecoaccount log
* improves code snippets
* drops add_deduction() methods for ecoaccount and intervention in favor of simpler creation in NewDeductionModalForm
* adds messages
* adds/updates translations
* adds support for DELETE method for all relevant objects
* improves get_obj_from_db functionality
* drops custom compensation logic for get_obj_from_db due to improvement of base method
* adds support for POST of new compensations
* adds shared_users property to BaseObject and Compensation to simplify fetching of shared users (Compensation inherits from intervention)
* extends compensation admin index
* modifies compensation manager which led to invisibility of deleted entries in the admin backend
* fixes bug in sanitize_db.py where CREATED useractions would be removed if they are not found on any log but still are used on the .created attribute of the objects
* adds abstract is_ready_for_publish method to PublishableObjectMixin which needs to be implemented in subclasses
* adds implementation for intervention model
* adds publishable check to rendering report view
* adds/updates translations
* adds tab titles for compensations
* adds/updates translations
* optimizes identifier generating, so that one-digit months will be converted into two digits
* adds mail sending if shared data is deleted
* adds/updates translations
* refactors recording mails into separate email template folder email/recording
* moves mail sending to celery worker using shared_task in konova/tasks.py
* adds mail sending for shared access given
* adds UserNotification settings checks for mail sending
* adds/updates translations
* 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
* adds file mime type check on NewDocumentForm
* adds file size check on NewDocumentForm
* adds is_xy_valid methods as classmethods on AbstractDocument
* adds translations for error messages
* updates help text on NewDocumentForm file field
* moves updating of shared access users into ShareableObjectMixin
* renames ShareInterventionModalForm to ShareModalForm since it's used for EMA and eco accounts as well
