#9 Allow auto processing for order by operation

[Will Hoover]

Allow auto processing of order by operation to traverse the property path for compound properties.

Currently, "addOrderBys(...)" methods in HibernateCriteriaUtil and HibernateDAO only use properties one-level deep. It would be better if they used a PropertyPath so that paths can be traversed when adding the order by properties. For example, adding an order by property of "myInnerModelPrimitive" works, but "myInnerModel.myInnerModelPrimitive" does not.
