Subject: SKILL_RETREAT

    This retreat skill allows a character to flee from battle in a
direction of his choosing and without loss of exp.  The main
disadvantage this skill has over FLEE is that it has a WAIT_STATE, so
you can't go ape with it like you can flee.
    One of the things I would like some help on is getting from the
direction argument to the interger direction... the way I do it
here(with a switch) is pure slop... is there a more efficent way?  Also,
if anyone has some helpful suggestions for cleaning this code up, please
teach me.
