[Royalphax]

Prevent tamed animals to aggro on its owner.

Bug fixed in cb35b5cb55df253e16310667eff51cb169068fa9, right ?

Edit: Not sure it's totally fixed:

1. I've checked quickly the code and it doesn't check the pet owner, so the tamed animal will not attack his owner, nor other players (not tested, not sure maybe this case is handle directly by minecraft default gesture).

2. (tested) llamas who come with itinerant vendor didn't aggro, but savage llama yes.
