Misc Changes

I've swapped out our previous Necroposting blocker for a system that will allow you to post to older content after notifying you that it's fairly old and confirming whether or not you really want to do it. Don't go necroposting just to test it, that would be considered spam, but if you try to reply to something older legitimately and see the new system, that's what is going on.

I feel like a hybrid system would be better. There's some forums that don't really need the new system *cough*Shenanigans*cough*.
