title: Sonarqube 5 - how do I mark false-positive?
body: <p>I've recently installed SonarQube 5.0.1, but I can't find where to mark issues as false-positive.  In the drop-down box where this option used to be, the only option is "Link to JIRA", and I'm signed in as admin.</p>
  
  <p>Is this feature now provided as part of an optional plugin?</p>
  
  <p>EDIT:  I have added a screenshot of exactly what I see in the UI.</p>
