Add modular configuration for Robust connectors

We can provide modular ini for connectors...

    look for our configuration in the following places...
      1) in the default ini/-inifile
      2) in the named file (ConfigName) located in the configured directory
            (see Robust[.HG].ini [Start] section for ConfigDirectory)
      3) in the repository named in the connector (ConfigURL)
           In this case, the file will be written into the configured
           directory with the specified

  See example connector/service @ https://github.com/BlueWall/SlipStream
  for testing.
