Add warband currency support (#5229)

Several state values for account wide currencies have been added:
- accountQuantity (sum of all account characters' quantity)
- realAccountQuantity (total account quantity after transferring
everything to your current character and paying the transfer cost)
- realCharacterQuantity (remaining quantity if all this character's
currency was transfered and paid the transfer cost)
- transferPercentage (transfer cost %)
- unitName (comes from currency API)
- unitGUID (comes from currency API)
- mainCharacter (bool value to check for the character you are currently
playing on)
