Although Moodle uses the coursemodule id to discriminate between activities, Turnitin doesn't have this and throws an error on creation if two activities have the same name, even if other details differ.

To fix this, the patch on github appends the coursemoduleid to the name of the activity in Turnitin. This allows alphabetical listing of the activities if a teacher wants to see them in the Turnitin interface, whilst keeping them unique.
