Feature request: Notifications for startup/receiving events

[jamessnowplow]

Whilst integrating micro into the js tracker testing setup we would have found it very handy to have some mechanism to notify us when micro had successfully started up. We ended up essentially tailing the log file for a particular line (not the most reliable long term approach).

It would be nice to have some kind of hook in or out. That might be as simple as an intentional line of output or could be something more complex.

While I'm making a wish list it would also be great if there was some similar notification on incoming events. We currently have to pause and hope its long enough for all events to make their way in.

If push came to shove we could certainly set up some kind of polling mechanism on the /all endpoint and achieve the same thing. Polling comes with its own issues though and a notification mechanism would be way more awesome.
