JMXConnector should support "jmxconnector" alias used by jmx-remoting.sar

For users that might of previously used jmx-remoting.sar. Add /jmxrmi alias for AS6+AS7. They could also later change their application for AS6/AS7 to use the "service:jmx:rmi:///jndi/rmi://localhost:1090/jmxrmi" URL.

This should be a one line change (I hope :

registry.rebind("jmxrmi", rmiServer.toStub());
registry.rebind("jmxconnector", rmiServer.toStub());
