Attempt to move the repeater of the damage effect client side, using entcs to get the player's origin. Previously, the server would send the effect to all clients every 0.1 seconds (lots of bandwidth). With this change, it will only send it once per damage event, and the client will find the origin and repeat it. Not guaranteed to work yet, and this commit might break it!
