title: custom html field in the django admin changelist_view
body: <p>I'd like to some little customisation with the django admin -- particularly the <code>changelist_view</code></p>
  
  <pre><code>class FeatureAdmin(admin.ModelAdmin):
      list_display = (
          'content_object_change_url',
          'content_object',
          'content_type',
          'active',
          'ordering',
          'is_published',
      )
  
      list_editable = (
         'active',
         'ordering',
      )
  
      list_display_links = (
          'content_object_change_url',
      )
  
  admin.site.register(get_model('features', 'feature'), FeatureAdmin)
  </code></pre>
  
  <p>The idea is that the <code>'content_object_change_url'</code> could be a link to another object's <code>change_view</code>... a convenience for the admin user to quickly navigate directly to the item.</p>
  
  <p>The other case I'd have for this kind of thing is adding links to external sources, or thumbnails of image fields.</p>
  
  <p>I had thought I'd heard of a 'insert html' option -- but maybe I'm getting ahead of myself.</p>
  
  <p>Thank you for your help!</p>
