[jboss-dev] EJB3 servlet regression

It's a war deployment which want references from a jar that's previously deployed. Since the MRMDRD doesn't do cross deployment resolving the test fails. The idea is to have an EjbReferenceResolver in the same way there is a PeristenceUnitDependencyResolver which can search the whole application server for EJBs. Don't use the FirstMatchEjbReferenceResolver, because it doesn't take scoping rules into account.
