title: dropzone amd requirejs issue
body: <p>I'm new to <code>requirejs</code> and I have a problem loading <code>dropzonejs</code> (<a href="http://www.dropzonejs.com/" rel="nofollow">http://www.dropzonejs.com/</a>) as an <strong>AMD</strong> . </p>
  
  <p>My <code>requirejs</code> config is: </p>
  
  <pre><code>requirejs.config({
  baseUrl: 'js/MV'
  ,paths: {
              ,jquery: '../libs/jquery-latest'
      handlebars: '../plugins/handlebars'
      ,scrolltofixed: '../plugins/scrolltofixed'
      ,logout: '../logout'
      ,dropzone: '../plugins/dropzoneAmdModule'
      }
  });
  </code></pre>
  
  <p>When I try to load the <code>dropzone</code> module with </p>
  
  <pre><code>function _activateDropzone(){ 
    require(['dropzone'], function(dropzone){
       var pippo = new Dropzone({ //..config 
  
       });  
    });
  }
  </code></pre>
  
  <p>it <code>logs</code> </p>
  
  <pre><code>Uncaught ReferenceError: Dropzone is not defined 
  </code></pre>
  
  <p>even if I'm loading the <em>dropzone-amd-module</em> . 
  Any advice?</p>
