Card Deck Improvements

Created by: Shadowmech88

Decks of cards now spawn with every card face-down, so that the dealer is able to deal cards without being forced to see what every card is. Cards added to the deck will be returned to face-down if they're not already. Creating and combining card hands is more versatile now. Other players can now see when a player flips a single card, so that they can see when the dealer's peeking.

I've also added a sprite for gambling table parts.
