Deploy hooks don't inform of failed deploys

[mhulscher]

The controller posts a callback as soon as a request comes in. However, a failed deploy, which does a rollback to the previous release, is not posted. This can cause confusion. Is this something that would be within the scope of the deployment hooks?

Sure! If you feel like taking a crack at this, the code lives here.
