Feature: view changes to model records

[DrumsnChocolate]

I think it would be neat to implement a page where we can select a model class and a record of that model, to inspect the changes that have recently been applied to the record and by whom. This should be feasible to implement, because we make use of paper trail in the backend.

That way, we can find out who's the culprit if undesirable changes to models occur, and we can revoke relevant edit rights.

Context: it has happened plenty of times that records are edited in a joking way by someone who should not be authorized to do so. We don't need to punish these people in any way, we just need to not let it happen indefinitely.

Other use cases can also be thought of, besides enforcement of proper permissions.
