Display content editor for sources

[sgroneme]

It is desired to give content creators and editors, especially from without CMO, more visibility. Therefore, for sources, it is desired to show the names of the people who were involved with source catalogue entries.

For a start, can we just use from the technical meta data "created by" and "last modified by" and 'translate' the username from there back into the real name?

I a second step, it is desired to add names manually (either from the users or with a free text field for external persons who don't necessarily have credentials to log in.
