  - Handle the 'generateHbm' integration test
  - Handle the 'generateDao' integration test
  - Handle the 'hbm2ddl' integration test
  - Handle the 'hbm2java' integration test
  - Properly fail with a MojoFailureException when the properties file is not found
  - Handle the noProperties case
  - Handle the 'transformHbm' case
  - Simplify the pom.xml file of the 'transformHbm' integration test
  - Some additional cleanup of the integration tests
  - Remove the unneeded reveng.xml files from the integration tests
