LDEV-3070: Fix few minor errors in Tools. Pass notifyCloseURL to proper authoring page in some Tools. Make generation of Tool content a non read-only operation as it starts a database transaction which is later used for writing.
CNG-6: Start LAMS lesson when adding it as MindTap activity. It allows setting correct viewURI from the beginning and removes the need to update it when running the activity, which is impossible according to Cengage. It also limits the number of LD copies: it does not get created when a Template is chosen, because starting a lesson creates a copy anyway.
Add "noopener" parameter to notifyCloseURL in single activity Authoring. Fix typos in icon toggling Javascript functions.
