Add winston

Added Winston logging.

This is the bare minimum for Winston.

Questions:

1. Where should we pipe logs, currently it's the Console however should we potentially do a file?
2. What else needs to be logged?

Let's leave this PR open until those questions are answered and this PR is a bit more substantial.

We might consider throwing logs to /var/log? Since you bring up logging, what is worth tracking under the auspices of #60? It's not really a log, but would go the same place, potentially. Something like /var/log/world might be appropriate in the way that a software like Apache has error, auth, and other misc logs.

Mostly, I think we're concerned with things that are of the different levels: warn, error and info, but what constitutes each is an open question. There have been a couple of moments recently when the daemon has gone down. I'd like to at least start with those.
