Ladder optimization

The ladder has been rewritten, and should be much, much faster now.

Sadly, this means the ladder's been reset again. I was going to convert the old database over, but no one could log in during the conversion (which could have taken days), so this was the only way to do it. Sorry.

Uh... look, a distraction! We've redesigned the Hangman system and I think it looks nicer this way. :)
