title: adding a `next` url to django admin change link
body: <p>In my django project I create a link to the admin interface so that users can edit the object:</p>
  
  <pre><code>&lt;a href="{% url admin:mode_change object.id %}"&gt;modify object&lt;/a&gt;
  </code></pre>
  
  <p>this works fine, but after the user finished editing the object in the admin interface, I would love to automatically bring the user back to the original URL (or some other URL). Currently, after the user modified the object, she / he ends up in the admin interface looking at all <code>model</code> entries. </p>
  
  <p>Is there a way to provide a return url to an admin link?</p>
