Added ability to toggle matching rarity for anted cards in the game's preferences. In the event that rarities cannot be matched, the game will fall back to the original system of choosing antes.

Added Booster Boxes to the quest shop. Added option to open booster boxes and fat packs one booster at a time to the preferences (default off). Re-worked FatPack class to accommodate. CardListViewers are now tall enough to hold the entire contents of a booster pack (15 cards) without creating a scrollbar (a 14px height increase).
