A new PSR-14 event is added that allows to modify the event right before
it is persisted within Destination Data One import.
This for example allows to alter dates, prices, etc.
Improve handling of missing end time in dates.
They sometimes use a different separator.
The code is adjusted to always use same separator and precision.
That will prevent the same location from showing up multiple times due
to different latitude and longitude values.
The code used native date functions, this made tests not robust.
We switch to TYPO3 API to fetch the current date and time.
Test is adjusted to define the date and time to verify code works as
expected.
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.

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.

* Add dependency.
* Remove empty tearDown() methods.
* Fix signature of setUp() to be compatible with recent phpunit.
* Temporary fix syntax issues in test files
