Clicking on login link from setup can fail with 404

Clicking on the "login to admin" link at the end of setup too quickly gives a 404 error. This has something to do with the way that we're using Jetty6. It would be best to change how the Jetty code works so that this isn't possible. A workaround would be to add a Javascript several second wait before the link becomes active. So, the page would display:

"Please wait, finishing setup..."

with an animated icon. After a few seconds, that would be replaced with the click to login message.
