ctrl-alt-del fix

[Harry Binswanger hb@xxxxxxxx]

For those running Xy4DOS and maybe other versions under Win95 and maybe
other windows versions:
You can reclaim the graceful way Xy has of responding to control-alt-del
(the opportunity to save open files before closing Xy) by assigning the
function EX to some other key combination than control-alt-del--which Win95
intercepts if you hit control-alt-del.
