The property will always be set in the future.
We no longer can use it as an indicator.
We switch to freq as new indicator.
We also ensure that start has to be given for a single date.

Both are supported during import from destination data.
But both were not part of functional tests yet.
They are added in order to ensure that future changes wont break import
of that data
It is now possible to create "Import" records in TYPO3 system.
Those records can then be imported via two new commands.
There is no need to configure everything within the command itself.
That allows:
* To allow editors to maintain import configuration.
* Have proper labels, description, csh and UI to create import.
It no longer is necessary to copy UIDs,
instead proper wizards from TCA are available to select pages.

The import already worked without category, but triggered a warning.
Tests were extended to always work with category, except in new test
case.
All tests were extended to check for empty logs in the end.
The import now checks whether category should be imported and ignores
further processing if not configured.
