Arrows deflect off of other players.

I was shooting with a bow and arrow, trying to kill him for stealing my diamonds.

Unfortunately, the arrows were deflecting off of him.
(This has happened in 0.6.0, I haven't tried it in 0.6.1)

1. Shoot someone who has joined you in multiplayer w/ a bow and arrow.
2. Take notice if the arrow deflects off the player and if it doesn't hurt them, or if it does.
