[JBCACHE-1000] JBossCache tutorial demo has been refactored to accomodate PojoCache one so that it uses the same embedded beanshell. PojoCache tutorial has been rewritten to have more similarities with JBossCache one, and has been extended with a section on Collections. Person and Address fields have been made private to promote encapsulation. Person no has a setLanguages(List<String>) to be consistent with get operation. This required fixing the ReplicatedPutWithBulkRemoveTest.
