Retrieves the horses owned by a creature.
The object that might own horses.
The Nth horse owned may be requested. (Default: 1)
This function will return the Nth horse owned by the target.
Returns OBJECT_INVALID if fewer than nN horses are owned.
If the target is mounted, the horse they are riding doesn't count, because it doesn't exist as a horse object. The function will only return the owner's dismounted horses.
