These pieces of jewelry help players remember locations on the world
map. Players can bind an amulet at any location on the world map.
Applying a bound amulet shows players a message indicating which
direction they should travel to return to the bound location.
Since this shares some code with the Rhyzian amulet, move the shared
code to CFWorld. While here, improve the getdir() function to round the
direction to the closest compass direction.
