[PR] Remove the "human" requirement from law 2.

[aft2001]

Notably, I'd argue that the 'chain of command' clause within Law 2 actually nullifies the issue of having to disregard commands from mutantraces - if a lizard captain and human clown have conflicting commands, you'd follow the captain's orders, as it'd violate the Chain of Command clause (as you'd be taking a clown's order as higher priority than a captain's) within Law 2.

For changelings and vampires, particularly ones that are a threat to the crew, you can disregard their orders, as the Chain of Command also includes security matters, and any crewmember or commanding officer that is a threat to the crew or station would have their orders disregarded as per the CoC.
