File sizes for uploads to course group portfolios may not exceed quota set for group's file repository. When creating a course, a quota can be specified. The sum of quotas assigned to all groups in a course can not exceed the total quota defined for the course (when the course was created). - client side and server side enforcement still needed here. Portfolio permissions modified to allow any user with group creation rights in a course access to all course group portfolio functions. All uses of words: group, Group, course and Course in "Course Groups Manager" now replaced with context-sensitive terminology provided by loncommon::course_type() and loncommon::group_term() which will supply appropriate text once a decision is made on Group vs Group. Currently "ANGEL-like Discussion Groups" are called Groups, regular courses are called Courses; and within regular courses sectionesque units are called groups, and within Groups they are called teams.
