Gets a list of:
 * last 7 articles in category:Review that are in the main namespace
 * a maximun of 4 articles (ordered by hasn't matched for longest time) that stable version != latest version for at least 5 seconds
 
Displays them in note up top. It only gets the 4 oldest oldreviewed articles as not to overwhelm the list. It waits for 5 seconds so that articles being actively edited and flagged don't show up
