LibCards+Solitaire: Elevate card highlight management to the card stack

Instead of indicating which individual cards should be highlighted, card
games now indicate which stack is highlighted. This lets the stack draw
empty stacks with a highlight (e.g. the Foundation stack in Solitaire).
If the stack is non-empty, the stack can delegate highlighting to the
top-most card.
