branch traversal via W quest artifact

Require the hero to pass the next_to_u() check when using the Eye of the
Aethiopica to portal to another dungeon branch.  Even though the reported
exploit of having a steed which is carrying the Amulet bring it along had
already been prevented, this changes the temporary portal behavior to be
like level teleport.  A steed carrying the Amulet or a non-adjacent pet
on a cursed leash will inhibit the attempted change of location.
