title: AttributeError: 'Settings' object has no attribute 'ADMIN_MEDIA_PREFIX'
body: <p>i am trying to make a smart menu using ChainedForeignKey, but so far i am stuck with the import of <code>ChainedForeignKey</code>:</p>
  
  <pre><code>from smart_selects.db_fields import ChainedForeignKey 
  </code></pre>
  
  <p>I am using pydev on Eclipse.
  I downloaded the smart select package here: <a href="http://pydoc.net/Python/django-smart-selects/1.0.2/" rel="nofollow">http://pydoc.net/Python/django-smart-selects/1.0.2/</a>
  and added it to my <code>PYTHONPATH</code></p>
  
  <p>when i debug i get:</p>
  
  <pre><code>Traceback (most recent call last):
