Keep edit history

[zorbathut]

This is a big project that we shouldn't really worry about, it's here just to put it in the list.

It'd be cool if posts included a full edit history. This should be an opt-out thing, where if a user wants to hide one of their edits, they can; importantly, "hide the edit" just means "don't include a link with the full edit contents". You can still see an edit was made, you just can't see the contents. (Unless you're an admin.)

This solves a lot of problems of people doing deceptive editing without making it impossible to edit.

This will probably be a bunch of work.
