Sam Atkins aac2488d5c LibCards+Games: Replace card "value" int with a Rank enum
Because `card->value() == 11` is a lot less clear than `card->rank() ==
Cards::Rank::Queen`, and also safer.

Put this, along with the `Suit` enum, in the `Cards` namespace directly
instead of inside `Cards::Card`. Slightly less typing that way.
