HEAD
Rewrote &getclasslist to use loncoursedata::get_classlist() and changed its
return values since most were not used.
Removed &reformat_classlist as this functionality is in
loncoursedata::get_classlist().
Modified all calls to &getclasslist to reflect new return values and to
only bother keeping the values they need (assigning unused return values
to undef).
