Resolving missing configuration files during start-up

If the server encounters a missing configuration file during a normal start-up of a new DirectConnect server (using AddServer), it creates a new configuration file and populates it with default values. However, if the missing file is an access service library file, the server does not create an access service.

In addition, if the server is configured for a snrf.tble table and one does not exist, the server creates a new one and populates it with enough data to allow DirectConnect Manager to create new access services.
