title: Audit tables not getting created/updated in hibernate envers
body: <p>I am struggling since last week to configure hibernate envers 4.2 version in my existing project. However the _AUD, REV_INFO tables do not get updated. I also tried to hibernate.hbm2ddl.auto to be create so that they get generated dynamically but no luck.</p>
  
  <p>As per new version I suppose I just need to add hibernate-envers jar in pom.xml and @Audited on entity class. 
  I am referring to below

  <p>for configuration. Can anyone please tell me what am I doing wrong. </p>
