Add CAH Fourth Expansion

I received my Fourth Expansion set a couple of days ago, so I thought I'd try and update HAH with the new cards. I noticed that there are no cards with numAnswers of 3, so I omitted one black card from Fourth Expansion which is a "Draw 2, Pick 3". Please advise on that point.

Also, I haven't actually tested any of this at all. I was careful about following existing formatting/conventions but that's really the only assurance I can give that this works. What's the easiest way to test the game locally?
