- Added a simple bank system. Users can deposit, withdraw and check the balance of their currency in the bank.

- Users can't check other user's bank balances.
- Added a button on a .$ command which, when clicked, sends you a message with your bank balance that only you can see.
- Updated pagination, it now uses buttons instead of reactions
- using .h <command group> (atm only .bank is a proper group) will list commands with their descriptions in that group
