	* gtkfilechooserimpldefault.c (struct _GtkFileChooserImplDefault):
	Added fields for the shortcuts tree and its model.
	(create_file_list): Don't call
	gtk_tree_view_column_set_sort_column_id() twice.
	(create_shortcuts_model): New function.
	(list_icon_data_func): Use an ICON_SIZE macro instead of a
	hardcoded value.
	(list_row_activated): Use _gtk_file_chooser_set_current_folder_path()
	to avoid converting the GtkFilePath to a URI string.
	(gtk_file_chooser_impl_default_set_current_folder): Select the
	appropriate item from the shortcuts list when the current folder
	changes, to let the user know where he is.
	(tree_selection_changed): Likewise.

	* gtkfilesystem.h (struct _GtkFileSystemIface): Added methods for
	::supports_shortcuts(), ::list_shortcuts(), ::set_shortcuts().
