Include TCGPlayer API ProductID in card info.

[jmcsmith]

Integrate the TCGPlayer API to have TCGProductID as a field on each card.
Category ID is always 1 for Magic
Each MTG set would have a group in category 1. For example Battlebond is group 2245
Each card then has a productid. For example Spire Garden is id 166659
Card data also contains an image link. https://6d4be195623157e28848-7697ece4918e0a73861de0eb37d08968.ssl.cf1.rackcdn.com/166659_200w.jpg

Inclusion of this data would allow developers using MTGJson to get TCG prices and link more easily.

This would be a good extension as soon as that system is in place. I'll see if I can write up a detailed proposal soon, hopefully next week.

I’d be in for a 4.1 to include this for sure
