Macro vial::run_with_banner

macro_rules! run_with_banner {
    ($banner:expr) => { ... };
    ($banner:expr, $addr:expr) => { ... };
    ($banner:expr, $($module:ident),+) => { ... };
    ($banner:expr, $addr:expr, $($module:ident),+) => { ... };
}

Same as vial::run!(), but allows setting a banner that will be printed to the console when your Vial web app starts.

You can use {} in place of the server's address. For example:

fn main() {
    vial::run_with_banner!("--> deadwiki started at {}").unwrap();
}

When we start this app, we'll see this:

--> deadwiki started at http://0.0.0.0:7667

Instead of the usual:

 ~ vial running at http://0.0.0.0:7667
