Throwable Lightsaber - Multiplayer Friendly

It's a lightsaber that you throw with right click, does damage to mobs and players, and returns to you. You can throw multiple out at once, and also use it with other players in PVP. Get the lightsaber with the /function lightsaber:give (no crafting recipe since I was focusing on the lightsaber itself, but you could easily add a recipe if you want to)
