HEAD
Bug 4853. Wording changes. Also can now configure automatic group enrollment during course creation when no sections exist. quota information (Mb) displayed to 2 decimal places. Eliminate javascript error on add members page when modifiying a course by removing setFormElements() onload in this case. Some replacement of gpterm with group now all groups will be termed groups, regardless of course type.
