Title: Add rake jobs:work_once. A one-off task that runs everything in the queue and exits.

I've found this to be useful for using Delayed Job in situations where I don't need a worker constantly running, or the tasks aren't pressing, or I want to save money on Heroku by running jobs with the [Heroku Scheduler](https://addons.heroku.com/scheduler) rather than on a separate worker dyno.
