Handle Pick 2+ cards

[kaiserfro]

Need a way to handle Pick 2, 3, etc black cards. This will take some restructuring of the application and interface. A simple select button isn't going to cut it for these.

The user would need a way to pick the cards in the right order and possibly preview what the result would be before committing to it. Then all of the other piping, sending the selected card list to the other players, and keeping track of the winner's cards all need to be dealt with. Additionally, after that round, you need to make sure everyone draws the correct number of cards.

Some of the internals seem simple enough, but I'm curious what others think about the UI part of it.
