Added SSL to broker configuration, then added code to config.js which will verify that ssl is present and if true override ipPort with tcp/443
Added SSL code to the config.js configuration verification script which will verify that if SSL is enabled for one or more workers, the SSL certiificate files are specified.  If SSL certificate files are provided in the server JSON files, then the certificate files identified MUST exist in the file system.
Fixed logical error in the config.js method for verifying SSL.
