PatR 0c70b1bd06 reset travel cache when changing levels ...

When travel fails to reach its destination, it remembers the target
spot to use as default next time.  But that spot is only meaningful
on the current level.  Discard last travel destination when moving
to a different level.

Also, discard unlocking context when changing level unless the
context is for a container being brought along (after having been
picked up since you can't unlock a carried box).  Previously, a
door pointer on the new level could happen to match the last one
being unlocked on the old level.

Discard trap setting context when changing level even if the trap
object is brought along.

Somehow the code for applying a touchstone got inserted in between
two sections of code for applying a trap (ages ago; probably since
touchstone was first introduced however many versions back), so
clean that up.
