Feedback hiding

Description

Adds authorization levels for feedback. This is to limit the details of feedback given to students, while allowing the TAs to see the full report. See eip/labrador/auta/auta-script-runtime-facade!1 for details on the model.

Resolves #227 (closed)

Changes

• Reports vary by the authorization level of the current user
• Errors are included in the report iff the user is an admin
• Spring auth roles are mapped to authorization levels globally, so these can be used for other purposes as well (and this is intended, resolving #184 (closed))
• A builder for AutaUsers as the constructor was getting out of hand
• A fix for CommentCounterGeneric returing integer percentages, while the metric type expected doubles. This was slowing down metric processing
