MASTERNOSEE flag (#1601)
Makes it so that if an actor's master is invisible due to camera/mirror/portal shenanigans, then the actor will also be invisible. Name based off of an Unreal Engine flag that does the exact same thing. Co-authored-by: Christoph Oelckers <coelckers@users.noreply.github.com>
