LibCards: Support "previewing" cards that may be covered by other cards

Browse source 
For example, in Solitaire, the vertical normal stacks cover the suit of
all but the topmost card in the stack. To see the suit of covered cards
the user currently has to move the cards on top of them out of the way.

This adds an API for games to set a card at a location to be previewed,
which will draw that card on top of all other cards without moving it.
