Improved curse debuff logic

[english5040]

• Existing curse rolls are saved and never rerolled until the blind is defeated
• If a card is copied, curse rolls are copied too (consistent with vanilla)
• If a card changes suit, say, and a curse becomes inapplicable, that curse roll is cleared.
  • If that card changes back to a suit for which that curse becomes applicable, a new curse roll is added
