Display content ownership / responsibilities
As an editor i want to define a content ownership in backend and display it in FE and BE. An owner ship must be a person and (or) a group.
AC:
- Select a fe_user as content owner for a page
- select optional a fe_group for a page
- display the content ownership in list and page module as info in BE
- display the content ownership in frontend (maybe in footer somewhere)
- add a contact form, to get in touch with content owner
