Location clue scrolls added a hint arrow when the player was nearby one
of the clue's locations. It did not, however clear that arrow if the
locations were changed and the previously-set hint arrow location was no
longer marked. This commit updates this behavior to clear the active
hint arrow each game tick before re-adding any location hint arrows.
(and if no NPC hint arrows are set)
