<Someone> wondered why there were no DOOR:nodoor specs for several doors in the
Samurai quest. I wasn't positive, but it seemed like these should have
been DOOR:closed, which is what I've added.
Alter the starting position of the monk and priest quest
nemeses to neutralize the possibility of attacking them by
zapping directly to the left as soon as you arrive on the final
level. And give the samurai a little variety too by varying
the arrival location, although that is just cosmetic.
