Implement Library's setting-aside effect

[amalloy]

I noticed

dominion/src/Dominion/Internal.hs

Line 425 in 2f4ff82

-- TODO this doesn't set aside any action cards.

- I think you want LibraryEffect to take a function like

libraryChoice :: [Card] -> [Card] -> Card -> Bool
libraryChoice cardsInHand cardsSetAside cardRevealed = -- choose whether to keep it

This isn't quite all the information available (eg, how many cards are left before my shuffle?), so maybe it needs to be lifted into State somehow, but I think it's close enough. If you agree, I think it's within my ability to make that change.

Perfect, this is what I was thinking too. If you send over a pull request I'll merge it in.

I've implemented this in amalloy/dominion@master...library - it's in a separate branch because I don't want to suggest you pull it until it's possible to test it.

You should be able to test this now.
