The vendor was renamed from `wrm` to `werkraummedia`.
And the namespace vendor was renamed from `Wrm` to `WerkraumMedia`.
That way all references to PHP classes as well as the package name
itself need to be adjusted.
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.
