title: Display user name in reference to user id in django template
body: <p>I expect this is an easy question.  For some reason, I don't have a solution yet.</p>
  
  <p>I have an object set from django reversion: version_list.  Each object in the set has a user id attached to it.  How do I grab the user names that correspond to the user ID's?  </p>
  
  <p>To try to be clearer, if each object in version_list has a name, date, and user id, how can I join the version_list set with the user table to figure out what user id goes with which name?  This is done in the view, or the template?</p>
