kts.GetFacing – return the current facing direction of a creature
result = kts.GetFacing(creature)
The input must be a Creature userdata object, or nil.
In the former case, the output will be a string representing the current facing direction of the creature.
In the latter case, the output is nil.
The return value is either nil, or one of the strings "north", "south", "east" or "west".
If the input is neither nil nor a valid Creature, then an error is raised.
