remove SCORM course format from core

Before adding this patch add some Courses using the SCORM course format and add a SCORM package to this course (ignore debugging/error messages on old code) Create some backups of the courses. Then apply the patch here and check to make sure those courses have been converted to use the singleactivity course format and still work (enter them as a student to make sure they still load) Restore some of the course backups to new courses. Verify the new courses work (enter as a student and make sure they still load). Restore some of the course backups to an existing course. Verify the courses work (enter as a student and make sure they still load).
