Very basic daemon infrastructure, plus MetaMTA daemon.

Summary: Amazon SES seems to be working well, except that it takes more than a
second to send mail in-process. Kick it out of process. (Between this and the
ImplementationAdapter layer, MetaMTA almost makes sense. :/)

Test Plan: Ran the daemon and got a flood of unsent test email.
