title: change the URL without changing the resource name
body: <p>I'm building a website for a rabbit farmer (let's pretend).  This man keeps a close eye on his rabbits, and wants them all categorized.  So I built him a RabbitCategoriesController, and added this line to my routes.rb</p>
  
  <pre><code>resources :rabbit_categories
  </code></pre>
  
  <p>The URLs are showing up as <code>rabbit_categories</code>, <code>rabbit_categoriew/new</code>, etc.  </p>
  
  <p>What if I want the URLs to look like <code>rabits/categories</code> <code>rabits/categories/new</code> instead?  This is <strong>not</strong> a nested resource, I just want to change the way the URLs look.</p>
  
  <p>Of course, if the resources were called "categories", I could do</p>
  
  <pre><code>namespace :rabbits do
    resources :categories
  end
  </code></pre>
  
  <p>Is there any way I can write that, but tell it to use the RabbitCategoriesController instead of the Rabbits::CategoriesController?</p>
