When mounting (right clicking) a horse, the player's rotation (crosshair) matches that of the horse's head. Instead, the player's rotation should stay the same. Could create a lot of potential for mapmakers that would like to enable right-clicking in their adventure maps (for example right-clickable fireball launchers, spawn eggs and 'guns') by using invisible horses and teleportation. Also a minor change to survival to make horses more smooth. Thanks!
