- Update/New icons for DC sub menus:
(Currently same icons for courses and communities)
- Icons for sub menu "Course and community creation"
(icon for "Display official course requests" still missing due to unclear functionality)
- Icons for sub menu after having selected a course with "View or modify a course or community"
- Use new "course/community configuration" icon for course/community settings as DC and for course/community configuration as CC
