sqlManager: new_order automatically puts order into sql input queue

[rongardF]

Orders instance has a reference to the SQL input queue and when new_order is called then new order is automatically placed into SQL input queue. There must also be a method close_order in orders object which accepts orders object and close steh order (automatically sending that info to SQLManager).

Investigate creating a custom broker which has methods for creating and closing orders, but also other methods like notify etc.
