- all commands have been moved to Console/Command (instead of just Command)
- job:list renamed to queue:show (other job commands take a job has parameter)
- upstart:control command exploded into:

  - upstart:info
  - upstart:start
  - upstart:stop
  - upstart:status

- fix a cli shortcut that broke the default help command
- removed dependency to SwiftMailer
