Allow set to be edited when you have multiple printings of a card from different sets.
Ever had multiple copies of the same card only from different editions? What set a card is from can change the value dramatically. Currently, the program assumes the card is from the most recent set and one needs to make a note of any inconsistencies. I'd like it to instead default to the most recent set with the option of changing it to a different set altogether if needed. It would be also be really nice if only the sets its actually been printed in show up in the scroll list.
