Write time-sorted record of each deployment

[lukebond]

Something is written on each deploy (see resources/config/model.js#L63) but it isn't sorted in a way that's useful to be presented in a time-sorted "deployment history" interface.

Perhaps something like:

key: journal!1429102560
value: { "event": "deploy", "timestamp": 1429102560, "key": "deploy!myservice!1" }

There may be other event types that warrant journaling, hence the "type" field.
