Several updates for SM era expansions (rarity values, secret rares, m…

…issing promos) (#43)

* Unified Rarity of "Rare Holo GX" cards

Converted the GX into upper case, and fixed newer expansion defining
those cards as "Rare Ultra" (which would be the wrong rarity)

* Added Rarity to all cards in Celestial Storm

* Added Rarity to all cards in Dragon Majesty

* Added "Sun & Moon - Ultra Prism" Secret Rares

* Added "Sun & Moon - Forbidden Light" Secret Rares

* Added "Sun & Moon - Celestial Storm" Secret Rares

* Added "Dragon Majesty" Secret Rares

* Added missing SM Black Star Promos, and removed rarity values

Promos don't have a set rarity, the previous submission tagged some as
"Rare Ultra" (which isn't the case; also added an empty field for old
promos without it, just for the sake of consistency)
