Bring back addFileNameColumn in directory/ file extract

As of Version 23.4 the distinct directory extract has been deprecated in favour of the option to select to extract either a single file or a directory within the file extracts. While doing this the addFileNameColumn option of the directory extract has been removed from the UI, but ist still functioning when added within the xml options and is working, as long as no changes are made within the UI.

To have this option reliably working I want to have the feature back within the UI, as it cannot be expected to the the xml code for additional features that do not appear within the UI. To get the same result without this feature I do need a least five building blocks (Connections, Extracts and Tableloop) of what would be possible otherwise which makes the codebase more clutered.

As only the UI Element is missing with the functionality already given and beeing present in the past there should be minimal effort in doing so.
