Many servers have factions, groups, etc that want to control their own independent economy from other factions. I propose the following:

1. Existing bank accounts will become international bank accounts (for compatibility). It should be possible to create new international bank accounts.
2. Add a currency card these will be used to identify currencies from each other.
3. Add a currency controller (or a better name). The owner of the controller will be able to assign an interest rate (and other options a government should control), there should be a trusted menu like the other blocks. Multiple currency controllers can control the same currency if they have the same currency card
4. Bank terminals (and blaze bankers) can be assigned to a currency by giving it a currency card.

cool idea
