Any member of a group can delete any comment on group pages

[Edward Murrell]

If a user adds feedback to a group view, any other member can delete it. It should only be the admin or the comment owner who can delete it.

    Add moderating roles to GroupType for comment delete. bug809625

    This change was added to limit deleting of comments in standard groups
    views to admins only, and admins and tutors in course groups. This commit
    adds the functions
        User::can_moderate_view()
    and
        GroupType::get_view_moderating_roles()
    to implement this functionality.
