Add attribute to @Tested for enabling "fully initialized" tested objects

[rliesenfeld]

For integration testing purposes, it would be very useful that @tested could still be used, with dependencies getting automatically injected with real instances (recursively) where no @Injectables were provided.

The main use case is the creation of integration tests for Java EE 6+ application classes. For example, tests for JSF backing beans which exercise the whole stack, including all EJBs and the database through a JPA EntityManager.
