title: Dropzone.js : stop adding to queue when event triggered
body: <p>I'm using Dropzone.js and would like to stop adding files to the queue when a certain event is triggered (maxfilesreached) to be precise.</p>
  
  <p>Let's say I've chosen 15 files in my 'Browse' window, but my maxFiles limit is 10. At the 11th, a maxfilesreached event is fired. At that point I want the 5 remaining files not to be added to the queue.</p>
  
  <p>Here is what I have for now :</p>
  
  <pre><code>init : function() {
                      this.on('maxfilesreached', function(e){
                          alert("I want to stop adding stuff to the queue here");
                      });
  </code></pre>
  
  <p>I want to cancel all future additions to the queue when too many files have been chosen already. How can I proceed ?</p>
  
  <p>Thanks in advance</p>
  
  <p>A.</p>
