title: Titanium Mobile Select File
body: <p>I need to get a dialog box to open, to select a file.</p>
  
  <ol>
  <li>To save a file, I need the user to choose a filename to save to</li>
  <li>To load a file, I need the user to select an existing file</li>
  </ol>
  
  <p>I can not find any file dialog in the API. Is there a method to popup a file select dialog?</p>
