Added "Muck Hand" button to the muck object, which players can click to muck their hand. Currently, the cards just teleport to the muck because setPositionSmooth does not remove cards from a player's hand.

The label on the Action button now changes to 'Done' when the players-click-action option is enabled.

Action should now start on the dealer after hands are dealt in a heads-up game.

Added two of my awesome change machines to the table. Feel free to delete them if you don't want to keep these eyesores around.
