Subject: [PATCH] Redirect users when they cannot access content (#48)

TNL-7171, TNL-7172, TNL-7173, TNL-7174: When a user is denied access to load courseware, redirect them to the appropriate location based upon the error code returned. If the error code is unknown they will be redirected to course home.
