title: Ordering admin.ModelAdmin objects
body: <p>Let's say I have my pizza application with Topping and Pizza classes and they show in Django Admin like this:</p>
  
  <pre><code>PizzaApp
  -
  Toppings      &gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;      Add / Change
  
  Pizzas        &gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;      Add / Change
  </code></pre>
  
  <p>But I want them like this:</p>
  
  <pre><code>PizzaApp
  -
  Pizzas        &gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;      Add / Change
  
  Toppings      &gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;      Add / Change
  </code></pre>
  
  <p>How do I configure that in my admin.py?</p>
