WIP: dms: show implicit predecessor successor fields
Several things are wrong with this and more generally implicit successor/predecessor:
- new UI is not tested, also for some reason from the web page we don't see the relation to image in new UI
- the web page should not have to have the image reference in the text like this ( this is a workaround that image links are not indexed in searchable text)
- are referenced /related documents proper terms ? this sounds reverse
