title: Setting UUID manually
body: <p>My server generates UUID for uploaded files, so i need to set UUID to the fileState after i received answer from upload server (to successfully use delete function). I added and implemented</p>
  
  <pre><code>setUuid: function(id, uuid)
  </code></pre>
  
  <p>In <strong>UploadHandler</strong>, <strong>FineUploaderBasic</strong> and <strong>UploadHandlerXhr</strong> to solve this issue but this involve editing fine-uploader sources, is there any other way around? I have feeling this can break something internally.</p>
