title: Case insensitive queryset sorting in Django
body: <p>Is it possible to sort Django queryset case insensitively? This query:</p>
  
  <pre><code>MyModel.objects.order_by('title')
  </code></pre>
  
  <p>uses case sensitive sorting. The result is sorted like this:</p>
  
  <pre><code>X..
  a..
  b..
  </code></pre>
  
  <p>But I would like to sort titles like this:</p>
  
  <pre><code>a..
  b..
  X..
  </code></pre>
