Better item equipping UX

[ECWireless]

• Right now, to update any character data (such as the character image URL), the player needs to sign
  • Instead, the player should sign a token when they first connect their wallet, which gets used each database update
• Additionally, we should allow users to equip and claim multiple items at once
  • Same goes for claiming classes
  • Requires a bit of design work
  • Involves batching transactions together
  • A bonus would be allowing users to claim and equip at the same time
