Provide an easy way to verify number of pages that are available to scan

[mgifford]

It should be possible to just provide a external link to a Google search like:
https://www.google.com/search?q=site%3Aaccessibility.gov

So we can roughly see how many pages there should be available to scan.

If Google thinks there are 600, but Domain Access only scans 50, then you know there's a problem.

This could just be a link from the list of domains here - http://localhost/audits/

Similar issue, simply knowing the number of known links to scan vs the Checked URLs. I think that sometimes it gets stuck, but I'm not sure if the script has come to an end, or if it simply doesn't know of any more URLs to check. I suspect sometimes this just needs to be restarted.

Knowing the % of known URLs vs Checked URLs would be a useful dashboard, particularly if scanning more than one link.
