Killer mechanics added!

Most likely the last feature for this game, I've added rules for learning more about the killer, and possibly fighting back.  Every time you trigger the killer's attention, you flip a card to see if you survive, as usual.  Now, the card flipped also gives clues as to the killer's identity and weakness, and once you've flipped six cards over in this way, you know the killer's weakness.  You can then, as a group, take action to fight the killer, and maybe even defeat them.
