HBX-3000: Maven GenerateJava Mojo should generate annotated entities by default

  - Change the default value of 'ejb3' in class 'GenerateJavaMojo' to 'true' to make it happen
  - Add file 'invoker.properties' for GenerateJavaWithAnnotations to only execute phase 'generate-resources'
  - Modify 'setup.bsh' for GenerateJavaWithAnnotations to create test database in basedir
  - Add file 'hibernate.properties' for GenerateJavaWithAnnotations so that the Person entity is generated
  - Modify 'verify.bsh' to verify that the Person entity is generated properly with annotations
