Removed dependency on embedded Jetty server and added Jetty maven plugin configuration.  Updated 900_Server.sh to use the mvn jetty:run configuration.  The default ports, HTTP: 8080 and HTTPS: 8443, can be modified by setting the -Djetty.port and -Djetty.ssl.port options.  These can be passed to the 900_Server.sh script by setting the environment variable LUMIFY_JETTY_ARGS; such as LUMIFY_JETTY_ARGS=“-Djetty.port=9090 -Djetty.ssl.port=9443”.
