title: Amending URL for "list_display_links" in Django 1.6 admin change list
body: <p>What I'd like to know is how do I change the URL that's applied to the items listed in <code>list_display_links</code> of an <code>admin.ModelAdmin</code> class? </p>
  
  <p>More specifically I would like <code>/admin/contacts/contacts/12345/</code> to become <code>/contacts/12345/</code>. </p>
  
  <p>All solutions I could find were quite old, somewhat convoluted and geared towards doing something else on top - so I was hoping there's some obvious way I'm missing. </p>
  
  <p>(I was kind of expecting <code>list_display_link_url</code> (or similar) to exist to over-ride in the <code>ModelAdmin</code>...)</p>
