When in condensed view, show a small icon link to the .io or URL

When you're not on the homepage it would be nice if we could see a :link: or :earth_americas: icon next to the repo name, or even in the sidebar :arrow_right:

Unfortunately I inspected the page and the DOM element containing the URL isn't just hidden, it doesn't exist. So we would have to retrieve this value from github itself and fall back on our interpolated version.
