Mho AI in progress, onJump completed

Jump was simple, Mho AI is proving to be tricky but I'm almost there. To
do: incorporate Misha's changes into my code (for example, using his
dead Mho code to kill Mhos when they run into fences), and make fancy
dialogue boxes with buttons. Then we should hopefully be done.
