create useful views to show (and undo) the changes made to objects

[sennierer]

ich #242 is solved and its clear whether the reversion plugin is creating useful provenance data we need to come up with views that allow useful interaction with the provenance data

views that allow useful interaction

reversion has an admin integration. is that useful or should it be something else? what are the envisioned workflows regarding the provenance data and who should be able to do them?

(In our project it only once occured so far that I had to restore a deleted entity and the admin integration of reversion would have been enough for me to do that)

Everyone from @acdh-oeaw/prosnet , feel free to chime in
