0.9.0

• Removed Template::from_file, you can still use Template::new to create local templates from strings.
• Templates has been renamed to Ramhorns.
• Added Ramhorns::lazy and Ramhorns::from_file, which allows you to do what Template::from_file could do before:

use ramhorns::Ramhorns;

let mut tpls = Ramhorns::lazy("./templates").unwrap();
let tpl = tpls.from_file("hello.html").unwrap();
