Allow to set a custom port on "init"

[stefanobartoletti]

As reported by the docs, right now config.yml accepts a custom value for the port to be used on the current installation.

I think it would be useful to have an option on the init CLI where users are asked if they want to specify this value, without having to manually edit the config file afterwards, pretty much like it already does for other options (i.e. username, password, email).

I will consider your idea, thank you :)

Thanks to you, this tool is awesome, and I'm testing it quite extensively these days.
