* Rework Scryfall Image Downloads
Now autoconverts collector numbers ending in "*" or "+" or "Ph" so not as many direct links required.
Uses a third attempt with &variation=true which is needed for the 79 cards that are marked as variations.
Fully tested image downloads with language set to russian to ensure fallbacks work correctly.
Restored comments to match scryfall names instead of the .java file names
Added check for api link ending in "/"
Added workaround comments.
Created prepareCardNumber in ScryfallImageSupportCards.java to use for the shared code.
A couple of comments of scryfall set names:
Commander Legends: Battle for Baldur's Gate
Game Night: Free-for-All
