[Games Database] Implement Tag or Image Type for Official Alternate Artwork

[Seth]

Image Slot for Alternate Versions of Game Box Art that were official: e.g. Greatest Hits, Player’s Choice, Early Promo Versions, etc., under the name Box - Alternate or some variation of that. Most alternate box art gets mixed in with the normal box art currently or with the fan art. Thanks - Seth
