MD10: Fixed bug related to the shifting of cards in opponents' hands.
-Opponents' cards no longer shift when the client plays a money card.
-Also added an initial implementation of the "MoneyInBank" property to the Player object. This keeps track of the amount of money a player has in his/her bank. The data associated with this property is not yet sent to the server.
-Added "None" type to the CardType enum.
-Added "EndTurn" type to the DataType enum in preparation for turn implementation.
