CONN-1161 (DirectHBM)

Rewrote Direct config DAOs to use a Hibernate Mapping file instead of JPA annotations.
I'm hesitant to deprecate -- if the issue is fixed in a future version of Direct RI and we decide to absorb that code, we will have to "un-deprecate" the function.

As for UnsupportedOperationException, I've been using the following at the service level on unimplemented web services: "throw new ConfigurationServiceException(new NotImplementedException());"  -- I'll add the same for the two Anchor save functions, especially since they are not referenced anywhere at the moment.
