Other changes include: * Eliminated the RKObjectFactory protocol and implementations. Object mapping instances themselves are now responsible for instantiating target objects for mapping. * Introduced RKObjectAbstractMapping superclass for RKObjectMapping and RKObjectPolymorphicMapping. * Updated example applications to use block object loaders (RKTwitter and RKTwitterCoreData) * Refactored method signatures of RKObjectMapper, RKObjectMapping, and RKObjectMappingProvider to reflect the existence of abstract mapping types. This was necessary to make polymorphic mappings integrate cleanly. * Fixed overlap in RestKit error domains between network and object mapping. fixes #208
