Migrate all crates to the 2018 edition

Browse Source 
Most of the CLI crates were already in the 2018 edition, and it turns
out that one of the macro crates was already in the 2018 edition so we
may as well move everything to the 2018 edition!

Always nice to remove those `extern crate` statements nowadays!

This commit also does a `cargo fmt --all` to make sure we're conforming
with style again.
