Introducing ecma_object_class_t type that describes ecma-defined object classes (value of ECMA_INTERNAL_PROPERTY_CLASS internal property); adding outer lexical environment's reference counter increment in ecma_create_lexical_environment; updating ecma_create_object to support object type field (that is not connected with ecma-defined object class, but is internal implementation defined type of an object).
