title: Open files always in a new tab
body: <p>I am using Visual Studio Code 1.3.1 with the newly introduced tabs.</p>
  
  <p>When I click on files, the first file will open in a tab. If I do not make any changes to this file, the second clicked file will open in the same tab.</p>
  
  <p>How can I avoid this and make Visual Studio Code always open a new tab?</p>
