title: Django fix Admin plural
body: <p>How do I change some models name from "Categorys" to "Categories" on admin site in the new dev django version?
  In the old version (whithout admin sites and admin models) you could just do this;
  <a href="http://www.the-dig.com/blog/post/customize-plural-name-django-admin/" rel="noreferrer">http://www.the-dig.com/blog/post/customize-plural-name-django-admin/</a></p>
  
  <p>However - now setting verbose_name_plural inside my modeladmin based class does nothing.
  Anyone encouter the same issue?</p>
