title: Change behaviour of help text in django form globally
body: <p>I want to take advantage of the default help text in django, but I don't like the way it's handled. I want to have:</p>
  
  <pre><code>&lt;tr&gt;&lt;label&gt;djangolab&lt;/label&gt;&lt;input&gt;djangoinput&lt;/input&gt;&lt;span&gt;djangohelp&gt;&lt;/span&gt;&lt;span class='onhovershowhelp'&gt;?&lt;/span&gt;
  </code></pre>
  
  <p>The last element is not provided by default. CSS on hover on '?' will change visibility for the help text span from hidden to visible.</p>
  
  <p>I want things to work out of the box so '{{form}}' will display as I want for any model form. So I want globally:</p>
  
  <ol>
  <li>Help text span by default with some attributes(z=1, hidden)</li>
  <li>Add another span to form row.</li>
  </ol>
  
  <p>I don't want to do this for every model form/field etc, use loops in the template and manually build this etc...</p>
