respond to Cale pull request comments. Update access.py (LMS) to use the same 'check for legacy group name first' logic. Add SECRET_KEY setting to the CAS project so that auth tokens from CAS are accepted in the LMS

adhere to the naming conventions of user groups (instructor_* and staff_* of the LMS AuthZ implementation). While we're keeping our authz.py implementation - which is duplicative of LMS's access.py - in order to minimize code churn/risk-of-regression, there is data compatibility so the two systems will interpret the data the same way

added toast notification styles and basic js implementation
