Disable winning rares for Chroma packs while there aren't any rare Chroma cards
Added rarity to everything, changed a bit how booster packs choose the rare cards. Also updated readme with more clarity. Is pretty much windows-only now, if it weren't already. Could not properly update the db, some cards showed as no rarity. Will fix tomorrow.
