Jeck - Please review. Shop antialiasing, multicolored card recieves gold texture.

* Moved shop text ("press square for other cards") etc, to ShopItems, so they rendered properly (all in one place, after AA)
 * The AA is really more a proof of concept than anything else. To do it properly I'd need a double-resolution copy of shop.jpg.
 * The real multicolored card has a greenish tint, and is darker. What do you think of gold.jpg? Should we tint it more that way?
