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)
added cookbook template code to run scorer on the scorer instance on boot
passed scoring url to template, fixed it
ensured creation of /tmp/scoring directory on scorer
scoring now only shows if an instance has the scoring recipe
Merge miles's changes, as they are needed or edurange is broken.
Fix templates, they had code which would not execute. Scoring_Url seems
to be nil a lot of the case
