title: Sublime exclude file extension in "File Search"
body: <p>I want to exclude a particular extension while doing a <code>Search in Files...</code> search:</p>
  
  <ul>
  <li><code>Ctrl + Shift + f</code>  in Windows/Linux</li>
  <li><code>Cmd + Shift + f</code> in MacOS</li>
  </ul>
  
  <p>I know it would be convenient to include extension rather excluding but  have so many extensions lets say 10 but it is tough to include 9 extensions like <em>.py,</em>.xml,*.html...</p>
  
  <p>I only want to ignore file 1 extension.</p>
  
  <p>anybody have any solutions??!</p>
