* refactors XYTableFilter classes to hold query_filter and checkbox_filter which are separate instances of django_filter.FilterSets
* improves render ability for frontend
* refactors table filters by introducing AbstractTableFilter, GeoReferencedTableFilterMixin, ShareableTableFilterMixin and RecordableTableFilterMixin
* adds full filter functionality
* refactors TableFilter inheritances for all objects
* refactors initializing and rendering of a map view into map/geom_form.html, which leads to simple includes on the detail views instead of redundant html
* refactors django-autocomplete-light form media links and scripts into dal/scripts.html, which can be included on the header blocks of detail views to support form modals using dal easier without the need for form.media
* changes filter behaviour on eco account index: instead of hiding recorded accounts (like in interventions), the filter option there has been replaced with "Show only unrecorded" which can be used to hide all recorded ones
* background: eco accounts shall be visible when recorded, since they can only be used for withdrawing if they are recorded. Hiding the recorded ones does not make any sense, just like in interventions
* updates some code documentation
* adds/updates translations
* renames eco_withdraws to withdraws
* adds EcoAccountTableFilter
* changes percentage withdraw to surface withdraw --> renames amount to surface
* updates EcoAccountTable
* adds column for rendering rest of available account using a progress bar
* adds progressbar.html to konova/custom_widgets
* adds/updates translations
* moves accessibility of compensations completely into related intervention.users set
* this way the visibility for a compensation can not differ from the one of the 'parent' intervention
* adds UserActionLogEntry model to user/models.py
* wraps user and timestamp info
* can be extended for more information in the future
* refactors all filtering and accessing on values
