* 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 GDALException in case of provided feature (import) without geometry content
* modifies 500.html template to inform the user about the admins being informed automatically
* adds clamping of 3D geometries to 2D geometries if uploaded using the map importer
* extends tests for payment-document linkage
* fixes bug in team-admin selection where autocomplete could not be resolved properly
* adds error message on intervention view if a payment has been added but no document has been uploaded yet
* adds same check to quality checker, meaning no intervention can be recorded which has a payment but no document
* adds trigger for sending data to egon on uploading a document in case of an already existing payment
* adds translations
* adds new 'generate_report' command
* generates TimeSpanReports for given conservation offices
* zips reports into archive
* sents archive to ADMINS mails
* 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
* enhances visualization of editable column on tables
* simplifies code
* enhances visualization of parcel_group column on tables
* WIP: Ordering on intervention table is odd. Same results are being displayed on page 2. Needs further analysis and fixing!
* disables ordering of parcel_group ("Gemarkung") column on tables
* ordering can not be done properly due to more complex nature of this column's content
* introduces "Keine Geometrie vorhanden" message instead of hour glass icon on entries where no geometry has been entered yet
* properly orders last_modified column by moving null values to the lower end of the ordering
* fixes bug where deduction of a recorded intervention could be deleted from the eco account detail view
* improves check_for_recorded_instance() logic
* improves rendering of detail view on compensation-like objects to highlight missing data
* fixes bug where geometry conflicts template message has been rendered despite having no active geometry conflict
* happened in case of existing geometry conflicts related to an as deleted marked entry
