Added original_citation attribute to the citation data model. Added include_additional_attributes flag to service definitions in services.yaml. Updated code and tests to accomodate those changes. Fixed typo in config name for item(s)_types_returned. Added delayStartup timers to cedilla.js and all tests so that we are sure configs have loaded. Cedilla.js now pulls port from application.yaml. Moved default service code to its own file default_service.js
