classes to eliminate issues with duplicated objects. closes #611, #612, #613, #618 * NSEntityDescription is now aware of the primaryKeyAttribute. Can be configured via Interface Builder within Xcode or programatically. * Added findByPrimaryKey: interface to the Core Data extensions. * Relaxed dependencies on RKManagedObjectMapping across the system now that primaryKey is available without a reference to the mapping.
