Added a new generic company available to everyone: The Citizens National Bank

The generic bank consists of the financial district building and gives multiple effect related to the investment pool. It is unlocked after researching "investment banking".

In addition to this, "societe generale de belgique" was reworked to now be a unique version of the generic banking company instead of being overly powerful and automatically being a best in slot in every case (sorry Generalist Gaming).

More Banks will follow soon.
