Blogging Roller

To prepare for the move to <a href= "http://hibernate.bluemars.net">Hibernate, I've been refactoring the current implementation of the Roller business tier. There is a lot of code in the Castor implementation of the <a href= "http://www.rollerweblogger.org/javadoc/org/roller/model/package-summary.html">persistence manager interfaces that is generic enough to be used in the Hibernate impementation. So, I'm moving that code up into abstract base classes that may be used by both implementations.
