It'd be fantastic if mobs registered as owned by the player were excluded - an improvement I'm suggesting as a direct result of trying to harvest crops and accidentally punching my dogs. (Either I'm clumsy or they're suicidal...)

Optional/nice to have: toggle for inclusion of mobs registered as owned by other players, allowing better control depending if you're on a peaceful server with friends or are playing PVP.

Fixed as of 96a0e40

I'll make tamed entities not able to be attacked via a config option. Thank you for the suggestion!
