* Set ``alternative`` to the ``description`` if available.
* Set ``creator_tool`` to the "destination.one".
* Set ``source`` to the URL of the fetched image.
The pages now receive proper cache tags.
The import now properly clears those cache tags.
That way all corresponding pages will show updated content after import
finished.
We need one test that executes frontend requests and import command.
The separation is therefore removed and tests are streamlined to have a
single parent providing all necessary information and setup.
The usual use cases right now would involve a new file with a new URL.
That way we don't need to download existing files again.
That reduced network traffic, execution time and resource usage.
Dates are vanished and re created during import.
Slugs for dates were generate after whole import was finished.
This is now changed to generate slugs for dates after saving each single
event.
A new TypoScript option upcoming is added.
The option can be set to 0 (default) or 1.
0 behaves the same way as in the past.
1 turns off the option useMidnight, start and end.
Only dates with a start date in the future will be shown.
