    Qt: don't append a second extension to save file names

    When checking if the file already has one of the possible extensions,
    MainWindow::fileAddExtension reuses file_suffix between iterations and
    appends to it each time, so it ends up checking for the wrong suffix for
all
    extensions except the first one. Scope file_suffix to the for loop to
    fix that.
