Replaced Rails with delayed job.
Remove dependency

Berkshelf can't find it, but its there, i promise
Remove really annoying sleep
Get the other env vars defined too.
Fixup some foodcritic complains.
Fix typo from food critic patch
Manually restart delayed_job

Make shure delayed_job's is restarted instead of relying on the opsworks
deploy script to do it.
