Store last sort settings in spreadsheet/sheet
Submitted by Sven Herzberg
It's a bit frustrating to have to reset all sort settings every time a sheet gets sorted.
a) Please save the last sort settings in the sheet object, so they are available if I need to re-sort the data without shutting down Gnumeric.
b) Please save these settings in the spreadsheet files, too (so they'll be available after restarting, too).
