Added dao dependency so the objects test plugin can include DAO tests
relating to the core objects.
Brought in the hibernate configuration files so I can try to reset the
database schema.  This is needed to setup the JUnit tests that work with
the DAO objects.  This could be improved with injection.
Added update patient tests.  This will require DAO functionality.
Altered configuration files to not refer to any classes except the core
classes.
Added hsqldb plugin dependency.  Still not working.
