title: how to make deoplete show autocomplete candidates as I type
body: <p>Now I get the list of candidates only after I hit <code>&lt;tab&gt;</code> (with 'supertab' installed).</p>
  
  <p>Can I configure so that candidate list pops up automatically as I type? (this is the behavior with YouCompleteMe).</p>
  
  <p>Thanks!</p>
