title: Set default for DisplayFormatAttribute.ConvertEmptyStringToNull to false across site
body: <p>The attribute, DisplayFormatAttribute.ConvertEmptyStringToNull has a default of true.  I would like to default it to false for the entire site (or by class or page would be good too).  Is there a way I can do this so I don't need to decorate each test form field with:</p>
  
  <pre><code>[DisplayFormat(ConvertEmptyStringToNull=false)]
  </code></pre>
