Changes how departing vehicles are handled: They are now restricted to the same flow-capacity as other vehicles driving on that link. Before, it was possible that driving vehicles were not placed in the buffer because there was no flow-capacity left in this time-step, but vehicles departing (=in the waiting list) were still placed in the buffer, effectively enlarging the capacity of this link. This could lead to situations where more vehicles left a link that should have been possible according to the specified capacity. Added 2 Test Cases to ensure this behaviour in the future, and adapted three test cases to this new traffic flow.
