title: Dropzonejs - Doesn't show progress bar / complete status and doesnt hide fallback form
body: <p>I'm using latest dropzone.js, version 3.2.0. I downloaded the folder and have all files needed. Using latest Chrome.</p>
  
  <p>When i drop a file, dropzone sends it to the server, and i successfully save it, but nothing visual happens on the front end. </p>
  
  <p>I guess i'm missing something trivial. How to make dropzone show upload progress animation?</p>
  
  <p>Another issue i have is that dropzone doesnt hide the <code>div.fallback</code> that contains fallback form.</p>
  
  <p>I thought those features supposed to work automatically.</p>
