* Allow multiple apps/environments to ship concurrently. Still can not ship the same app to the same environment at the same time, duh.

* Support new options to 'force' a ship, allowing the ship method to perform extra sanity checks on your ship to ensure you don't shoot yourself in the foot. (E.g, don't allow someone to ship a branch that is <N> seconds old, it's likely a mistake)

* Improve the output you see when shipping (full dumps and always output after a migration)

* Level up the rewards for shipping to production.
