gui: provide prefernces for the file browser's directory at startup

  line edit / file dialog for setting startup directory

* settings-dialog.cc (constructor): init new input widgets from settings,
  connect needed signals;
  (write_changed_settings): write values from new widgets into settings file;
  (get_file_browser_dir): new slot for settings octave dir in a file dialog;
  (get_dir): common function for settings dialog slots;
  (get_octave_dir): use get_dir;
  (set_disabled_pref_file_browser_dir): slot for disabling some setting widgets

* settings-dialog.h: new slots get_file_browser_dir, get_dir,
  set_disabled_pref_file_browser_dir

* files-doc-widget.cc (constructor): set start directory depending on settings
