The objective of this fix is to make a tap on a card more positive-feeling for the player and not to disappear silently if it is interpreted as a drag. It adds a Base Card to make an empty Stock Pile behave as a Card and use the tap and drag logic of the `Card` class. Any attempted drag on a Stock Pile card, including the Base Card, is now changed to a tap in onTapCancel() and the drag is not followed. The Base Card is rendered in outline only and does *not* take part in gameplay. In other Piles a short drag is either treated as a tap or ignored. Only the Waste and Tableau Piles allow such taps. As before in Klondike Step5, they result in the tapped card moving automatically to its Foundation Pile if it is eligible to "go out". As before in Klondike Step4 and Step5, all piles except the Stock Pile allow drags to start on them and they can finish on a Foundation Pile or a Tableau Pile. Closes #2890. When testing, try sliding the finger or mouse slightly while making a tap. --------- Co-authored-by: Lukas Klingsbo <me@lukas.fyi>
