Added view to GradingSurveyGroup to list all records for a specified group.
This view will later be extended with options to start Tasks for collecting the data and processing it.
Add scope view for GradingSurveyGroup and set access checks.
The access checks are now properly set for create, edit and show. To facilitate the scope view the access check have an extra check built in to ensure that a scope is actually present before cheking for an existing Program.
