Issue:
Teachers can edit grader report preferences (including switches for quickgrading and
quickfeedback), but do not have access to the "Turn editing on/off" button, so they
can't do quickgrading.
Solutions:
1.Decouple the quickgrading and quickfeedback modes from the editing mode,
and turn them on/off through the preferences page. New capability: moodle/grade:edit
* preferences: don't show quickgrading if no capability grade:edit
* If quickgrading is switched off as a preference and user doesn't have manage cap, show edit icons around grades when in editing mode
The number of submissions in the Group average and Course average calculations
should be shown in brackets. (submissions) should be added after the Group average
and Course average labels.
Solution:
new grader report preference (Display number of grades in average cells).
