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.

Most of the time dates are fetched and shown.
They need the event to show info like title.
But they nearly never need further dates, except in detail view.
Turning this property lazy will save a lot of data fetching and mapping
and provides a huge performance impact.
The properties should always be ObjectStorage instances.
We streamline the annotation and initialization to ensure exactly that.
Also import needs small adjustment as it still expected null as possible
return type.
The process will not call __construct, the object storages might not be
initialized. Therefore initializeObject is now implemented which is
calling the existing method to initialize object storages.
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.

Given: Website uses copy / free mode of localization.
and Editor selects specific events to display.
Then: Those events should be displayed as selected.
Before this change the sorting was applied on uid of objects,
which is the uid of default lanugage record. But editors might select
localized uids. Therefore a fallback is added in case no object was
found.

Add new record type partner.
This can be something like a media partner or something else.
Allow an event to have zero or more partner.
Add necessary files and models with relations.

Allow editor to reference TYPO3 page records from events.
E.g. used to provide further internal information links.
Also those pages are resolved via DataProcessing.
That allows integrators to be 100% flexible to resolve those page info.
By default a menu is generated and media is resolved.
Also validation is ignored, as this improves performance and allows to
use the new class as injected property without validation fails.
Models are not managed via frontend and therefore don't need validation.
