Trade Hub Revamped

[luketd]

• Add section for traders to put cards they own on the block and cards they want.
  - Do we want to limit how many cards they have on the block / what they want
  - Do we want, on trade accept remove cardID if they traded for it
  - Design of it all
• In the cards selection section instead of grouping by ownedCardID its just by CardID
  - On selection it will pull one of the ownedCardID. Will have to think about how to add multiple of the same cards.
  - Then we can add sort from least to most
  - Maybe better filtering options / UI for the user (like the bank filters on portal)
