Fixed a bug which did not allow attempts to modify students if the list had
been sorted.
CSV printout of classlist now includes an extra column specifying the users
status if the status mode is set to 'any'. If it is set to 'expired' a
brief message stating such will be printed out at the top of the sheet.
