#198 Filemanager editor sometimes destroys the .mnu layout

[Bernhard Grün]

If you edit a .mnu file with the filemanager editor and
that file has more columns than the editor window the
.mnu file is broken after saving.
The problem is that some lines are wrapped so the .mnu
parser can't understand such files anymore. In general
the editor has no right to wrap ANY lines. So we have
to fix the file saving routine and NOT the .mnu parser.
