I picked `bunyan` as the logging module. It has some nice features and is heavily used at Joyent. I've got it set up to write to a rotating file that splits once a day, with a 7 day backlog. The `ringbuffer` stream is meant for core dumps and possibly a REPL (if we add one) and when we aren't in `production` also write to `stderr`

One *meta* note: hapi style logging kind of clashes with bunyan. At first I liked how hapi only has one log function with tags, but now I don't like it at all. Doing multiple checks on every log call is silly. The hapi to bunyan log line conversion needs more work, but it's basically working.
