Title: allow access to unprotected subojebcts for PersistentResourceDirectory

PersistentResourceDirectory the class has no security assertions, therefore it was not possible to use restrictedTraverse to access theme content.
this patch sets __allow_access_to_unprotected_subobjects__ to True on PersistentResourceDirectory (as with FileSystemResourceDirectory)
