Merge branch 'master' into james

* master: (33 commits)
  scoring just about works!
  scoring even closer to working, moved scoring related files into scoring.rb (note: for some reason scenario.scoring_page_contents doesn't work, it's not writing to the object in s3
  moved scoring_url and scoring_page setup to ymlrecord (temp, to fix but okay for now)
  Fix templates, they had code which would not execute. Scoring_Url seems to be nil a lot of the case
  scoring now only shows if an instance has the scoring recipe
  ensured creation of /tmp/scoring directory on scorer
  passed scoring url to template, fixed it
  added cookbook template code to run scorer on the scorer instance on boot
  changed scoring to be a role, changed instance boot to check for scoring role (sort of temp solution, but should work until we switch providers)
  Update readme.
  moved scoring_url code to cookbook
  moved scorer back to its own subnet (cue yakety sax)
  moved scorer back to nat subnet
  removed .ruby-version from the repo
  removed unnecessary info in instances view, changes scorer os to ubuntu
  successfully got answers_url and scoring_pages onto the scorer
  Add name lookup hash in order to support multiple scenarios of same name
  scenarios -> scenarios-yml
  ensured edurange-answers bucket is created
  Incomplete merge, apologies
