Deploy spec11 reporting to production

This turns on spec11 reporting in production by adding it to the cron.xml, generating the report and sending an e-mail with a list of all problematic registrations to the associated registrar on the 2nd of each month at 15:00Z (11am EST)

This also tweaks the e-mail template a bit according to suggestions from Bruno.
