Subject: [PATCH] New data structure in CardEdition allocated for quick
 cardInset lookup

CardEdition now includes a new Map data strcuture that is allocated only if necessary (i.e. when lazy card loading is enabled) and it will be used for faster card in set lookup by card name. The Map will return a List of cards to account for multiple versions (prints) of a card with the same name within a CardEdition
