mod_external_services: Validate services added via events While writing developer documentation it became obvious that i was silly to have one item format for config and items API, and another format for the event API. Then there's the stanza format, but that's a common pattern. This change reduces the possible input formats to two and allows other modules the benefit of the processing and validation performed on items from the config.
