Adapt to changed module slot for Hibernate OGM

smarlow@redhat.com, we'd like to alter the module name + slot we use for Hibernate OGM (See OGM-698). Currently it's name="org.hibernate" and slot="ogm", we'd like to use name="org.hibernate.ogm" and slot="main".

IIRC, this requires some change in the ORM integration code (JipiJapa). Could you do that change (or point me to the right place, then I can try to do it myself)? Thanks!
