title: Allow outside touch for DialogFragment
body: <p>I have a <code>Fragment</code> in my app that shows a <code>DialogFragment</code>.<br>
  I have in the fragment a button that closes the dialog. But when I show the dialogFragment, the touches outside from the dialog do nothing and I can't click the buttons outside from the dialog fragment.</p>
  
  <p>How can I allow outside touches for DialogFragment?</p>
