Create a String literal

This provides a slightly shorter alternative to creating a String from a literal.

Examples

Empty strings:

use string_literals::s;

let old = String::new();
let s1 = s!();
let s2 = s!("");
assert!(s1.is_empty());
assert!(s2.is_empty());

Non-empty strings:

use string_literals::s;

let old1 = String::from("Alice");
let old2 = "Alice".to_owned();
let old3 = "Alice".to_string();
let new  = s!("Alice");
assert_eq!(new, String::from("Alice"));
