Debug logs and transaction false

Replaced some old commented out printlns with debug log statements

Made all remaining services non-transactional.
Grails has a default of using hibernate to start transactions in services unless you specify otherwise in each service. Since we don't use hibernate for a database for any of our services, we don't have justification for the added obscurity of Hibernate errors wrapping genuine runtime errors. We're better off turning off transactionality on all services.
