title: Make Bootstrap Carousel navigation show only on hover
body: <p>I was using Bootstrap's Carousel, found <a href="http://twitter.github.com/bootstrap/javascript.html#carousel" rel="noreferrer">here</a>. It's a great script, unfortunately, I'd like for it to be able for the navigation arrows to go away and only appear on hover. Is this possible and how would I would go about implementing that?</p>
  
  <p>Thanks for all help!</p>
