Ratings field within Bootstrap using Font Awesome stars

I looked around for a nice easy rating field using stars. Just like the ones you find on tripAdvisor. All the solutions looked a little CSS or JS heavy and needed images which are more HTTP connections.
So my solution uses only a little CSS, a small amount of jQuery and font-awesome. You'll have to get font-awesome for it to work.
See below.
