Add new rarities

[Aviortheking]

Currently there is multiple rarities in the TCG, Common, Uncommon, Rare and ultra Rare(white instead of black) are the four most common with their symbols on the cards itself.

A Card HAS only one rarity (unless the TCG change).

some other cards have a rarity of "Holofoil Rare"/"Rare holo"/"Holo Rare" and while they could be used in the rarity field it would be redundant with the variants.holo field.

So it would mean that the following rarities will be used in the v3:

• None // no rarity is displayed
• Common // the circle
• Uncommon // the diamond
• Rare // the star
• Ultra Rare // kept because it is officially kept (in the japanese at least) // Pokemon EX,LV.X,PRIME,GX,Tag Team GX,V,VMAX
• Rare LEGEND // the star is yellow
• Rare Star // the star is to be white with a yellow border
• Amazing // an A in a rainbow
• Secret Rare // number is beyond the official one
• Shining // has three Stars
