	* gtk/gtkpathbar.c (get_dir_name): Don't special-case Home and
	Desktop; just use their real names on the file system for the
	user-visible names.

	* gtk/gtkfilechooserdefault.c
	(gtk_file_chooser_default_class_init): Add a "desktop-folder"
	binding signal, and bind it to M-d by default.
	(desktop_folder_handler): Implement the default handler.
	(home_folder_handler): Use a helper function.
	(switch_to_shortcut): New helper function.
	(shortcuts_append_home): Don't special-case the name of "Home";
	just use the folder name.
