Can't get all child-sites recursively
Previously I wanted to get all children of a site recursively.
Unfortunately I could only get the site's children but not the grandchildren.
Therefore I implemented my own method to do that:
https://dev.quiqqer.com/quiqqer/redirect/blob/master/src/QUI/Redirect/Site.php#L36
Maybe the Site's getChildren()-method could get a parameter to also get it's grandchildren.
Or maybe a/my method could be added to the Utils module, so this functionality doesn't have to be implemented over and over again.
