make riftsaw-ode uses the jpa-hibernate as default dao provider.

Right now, we've defined the default_dao_factory, store_factory in OdeConfigProperties.java by using jpa-openjpa. we should be changed this default value in our codebase to use jpa-hibernate.
We do have run three dao providers (dao-hibernate, jpa-hibernate, jpa-openjpa) in the bpel-test, bpel-store module, but for riftsaw, we've just concentrated on the hibernate as dao provider.
