OK< due to a few remaining issues, tamed mounts will no longer "remember"
players who have attacked them. This means, for example, that if you jump off
your horse and run away during a fight with another player, the mount will
stop fighting and wander off to graze. It also means that you can kill just
about any tamed mount with little to no difficulty, but at this point, I'm
willing to declare that the lesser of two evils.
