Many changes to deal well with the new status field.
The routine &show_class_list was modified to use javascript to set a few
hidden parameter values and submit the form in order to take you to the next
page when modifying a students information. This is in contrast to the
previous method which passed parameters in a link.
&show_drop_list is now a little brighter about the 'sortby' parameter, for
what it's worth (not much, really).
&drop_student_list acts more intelligent on errors - the errors are still
reported and other information is now suppressed if it is not relevant.
Specifically, if no students were successfully dropped you needn't tell
the user about re-enrollment.
