Switch to relative URLs

[jeffposnick]

Many of the URLs within the source are absolutely, starting with /. This makes it more difficult than it needs be to deploy somewhere that isn't the root of a domain.

E.g. xhr.open('GET', '/sounds/airhorn.mp3' ); would be more flexible if it were xhr.open('GET', 'sounds/airhorn.mp3' );

There's another case where / is used as the scope for the SW registration, and that's an anti-pattern. / will never be valid unless the registering page is also served from the top-level, and if that's the case, you might as well just leave it with the default scope of ./.

All of the references to '/' should be replaced with window.location.pathname which would fix the problems.
