Since this means there's multiple possible answers, I made it so that the
answer can now be a function, and that gets run with the guess. This may
open the door to other puzzle ideas that have been ignored due to having
more than one correct answer.
The list isn't "complete" in any sense, and it may seem somewhat arbitrary,
but I didn't want to just dump a massive file I found online into it. It
should work perfectly if you want to do that though.
