plugin XEP-0060: async sendItems + precondition-not-met policy: - sendItems is now an "async" coroutine, and sendItem use it instead of duplicating publication logic - policy to use when a precondition is not met (with publish-options) can now be specified, for now it's either raise the exception (default policy), or try to publish without the options - constants have been added to handle "extra" keys
