Refactored the service response to a separate Interpretation-message. listen and interpret now publishes this message to a topic, for anyone to listen an respons to interpretations it can process. Moved the listen_and_interpret-node to the src dir
Made interpreter for sending e-mails. Depends on some configfiles, this could be replaced by (some) yaml files. Committing files with passwords isn't to clever, so that is in the uncommited configfiles
