Adding a field to specify broker port in client page

[DavidObando]

This is just in order to make it easier to select different ports when multiple brokers are running in the same host.

This is not a must-have, but it makes monitoring brokers much simpler.

one more option/checkbox could be ssl

i already added this - useSSL: self.port() == 443 , to infer the use of SSL. So the checkbox is not needed.
