Set up calls to delayed_job method
Refactor delayed job as queue
Refactor job queue back to a delayed call

Added Resolv DNS call method (:ip_lookup!) to Domain model. Not sure if
that sort of activity is good practice for a model, but several sources
online advocated. Maybe after setting up reliable tests for this
behavior I can look at whether this should be moved somewhere else.
Merge branch 'master' of github.com:scooter-dangle/spirit-app

Tweaked some things remotely. Merging back in.
Change back to Ruby 2.1.1

Not ideal. May need to change later. Rbenv ruby-build issues :(
Add tests for :ip_lookup! (after implementation  :(   )
