- General course settings: users allowed to clone course.
- Show if domain default is set.
- Adding any course-specific setting will cause domain default to
be ignored.
- For official courses, where localenroll::instcode_defaults()
has been customized, can also allow cloning by specific
partial institutional codes (e.g., department + number: such as
phy184 for example).
