Title: Add document date to listing block if ftw.file is installed.

We need to be able to display `Document Date` in the listing block.
The `Document Date` is a custom field defined by `ftw.file` (which also registers an index and metadata).

This PR makes the `Document Date` available if `ftw.file` is installed.
