Endermen not attack player.

Endermen should attacked player after provoke or attack Endermen first
.

Endermen not longer attack player endermen only open the mouth and come to player and teleport away but the sound only come to player.

rplatham update based on comments:
When playing on a realm with another user (but apparently also in single player) an aggravated enderman will move towards the player but teleport a few blocks away instead of attacking. The enderman never attacks. I could not reproduce this in single player spawning enderman one at a time from eggs. Although sometimes the enderman would teleport away instead of attacking, especially.more frequently if I was looking right at it, I was attacked at least some of the time (especially when not looking at the enderman or at night).
