Title: Attack rework

Added layer threshold for projectiles,so that ranged projectiles don't stop at pipes and cables.
Also added the ability to hit mobs when you click an atom below the layer threshold on that turf.
It depends on intent, "harm" for weapons, anything but "help" for empty hand so you can even disarm and grab.
This will help people how don't have super ping.
