Remove sucker punch

Short-lived processes cannot launch threads (specifically Resque jobs), and there was no easy way to disable sucker punch in those cases.  Best effort was to put the entire app into "test mode".  

This removes it, and leaves the job of backgrounding these things as an exercise for the user.
