title: How do remove a project in qt creator?
body: <p>When I right click a project, the "Remove project" menu is disabled. Why?</p>
  
  <p>I tried to remove the .pro file which gave me a confusing result.</p>
  
  <ul>
  <li>First I got a message that I could not remove it.</li>
  <li>Then I got a dialog asking if I also wanted to remove it from version control.</li>
  <li>Finally, I got a messge that the file was gone, clicking it confirmed its non existence, it is still visible in the "projects" treeview however.</li>
  </ul>
