Quite useful when launching using port=0 to use a random free port.
This is great for testing, this way we can run many tests in the same time without any port blocking.
So this is really more flexible this way, and much easier to write application supporting CGI, FCGI, Nino and so on .. as demonstrated in hello_world
This is a first version, more will come later, mainly migrating from Eiffel Web Reloaded to this Eiffel Web Framework project.
