Profile edit history

[raccube]

Having an edit history of user profiles would be very useful for moderation.

@nilsding fun coincidence because I actually looked at it for #105 today

We intially made this because one moderation case came up where something like this would have been relevant, but the amount of data we'd have to store with all the profiles edits and how rarely it would come to use probably makes this idea a bit overkill.
