Title: Print when we're listening, for use in automated browser tests

Similar to #1884, for testing with [Sauce Labs](https://saucelabs.com) which run tests directly in the browser, we need to know when Meteor is ready so that we can start running tests. But we also want `--once` so that Meteor fails fast if there are errors.
