GUI: data dialog: convert Line Feeds if escaping on input, escape on output

and set Escaped flag; fix tooltip that they're converted to spaces;
  sequence dialog: re-organize to put Create Sequence stuff only in groupbox
  and put Import -> From File and Clear at bottom, similar to data dialog;
  mainwindow: use new Escaped flag from data dialog and set checkbox and
  statusbar message accordingly
