clap::crate_version! with yaml

[kenoss]

If I'm correct there's no corresponding way to set version by crate_version! with yaml cli definition, right?
I think it is better that this is the default.

The convention is to set it right after importing the yaml:

let yml = load_yaml!("cli.yml");
let matches = App::from(yml)
    .version(crate_version!())
    .get_matches();

Wow it's cool!

Thank you for helping.
