Group support

[ghost]

Currently in the 3.10 version, if a course is set for Separate groups, and the groups consist of a Teacher and some students, the block does not respect this, but instead shows all the Teachers in the course.

Clicking the Participants link, of course, does respect this, so some Teachers may show up on the block but not on the Participants list for a student.

The same situation happens if the Non-editing teacher role is allowed, as in the case where a course has many Teaching Assistants with students assigned to them by group.

It would be very useful in courses with Separate groups that the block respect these views.
