Script Summary: Automatically refreshes all "hidden" update pages, and alerts you when a link is found.
By the way, please don't leave this script running for a long time! If lots of people run this script on the same time, then it would be like DDoSing Valve's server, and we don't want that to happen! In other words, don't leave this running overnight! A minute should be enough to see if any link exists on the page.
