Basic progress updates
Clean up HTML
Add jQUery-ui
Implement progress bar and win notification

Add a progress bar using jQuery-ui rather than just a n/m display. The
progress bar is default styled just like everything else.

Switch to the google CDN hosted version of the ui-lightness jquery-ui theme
because I think it looks a little better than smoothness.

Expand the sample text so it is clearer that the progress bar works.

Add an alert()-based win notifcation so I have a hook for updating this with
some real animation later?
