It is now possible to group locations.
Each location can have arbitrary children.
That can be used for editorial structuring.
Filtering for a location will always find all dates where the location
or one of the child locations is assigned.
One use case can be to group imported locations and provide a grouped
location for filtering in frontend.

A new class is added which will add meta tags for dates and events.
The class has an interface which allows it to be replaced via DI to
alter behaviour.
Refactor import regarding data handler. We now also need to add a new
column "keywords". We use the new DataHandler approach.
But that approach only covered relations so far. We therefore refactor
that area to be more generic and use that one for new keywords column.

It was not possible to change the value of highlight for events due to
broken TCA.
This got fixed. The input is now streamlined to look the same as hidden
to not irritate users.

Destination Data One provides an source info explaining where the data
originally came from.
This is now added to event records and exposed in TYPO3 backend.
That allows editors to check the source and contact corresponding
sources in order to fix broken 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.

Extbase will properly use mm sorting.
But categories can't be sorted within the TCA tree component.
Therefore it makes more sense to use actual sys_category sorting.
In order to do so, we add our own model and pass the sorting.
That way PHP can do the sorting.
That's the easiest approach.
Also events shouldn't contain to many categories. A performance impact
should not be high.

That has no effect, the info is just available from model.
This can be used to display a canceled date in a different way, or
render a notice.
