U614 - Master Kaen death message

rewrote the message so it doesn't talk about his body dissolving into gas,
since there's a possibility that he'll leave a corpse.  It now doesn't
mention a body at all, so it's not so bad when he doesn't leave a corpse
either.  The contents are completely changed, and I think it's more in line
with the sort of thing you'd expect from Master Kaen.
