Marcus Karlsson c39b6be22b docs: Fix name of GtkFileChooser's Create Folder button
The documentation for GtkFileChooser references the button which allows
the user to create new folders as the New Folder button, although the
label actually says Create Folder.

Update the documentation to say Create Folder instead of New Folder.

/**
* SECTION:gtkfilechooser
* @Short_description: File chooser interface used by GtkFileChooserWidget and GtkFileChooserDialog
* @Title: GtkFileChooser
* @See_also: #GtkFileChooserDialog, #GtkFileChooserWidget, #GtkFileChooserButton
*
* #GtkFileChooser is an interface that can be implemented by file
* selection widgets. In GTK+, the main objects that implement this
* interface are #GtkFileChooserWidget, #GtkFileChooserDialog, and
* #GtkFileChooserButton. You do not need to write an object that
* implements the #GtkFileChooser interface unless you are trying to
* adapt an existing file selector to expose a standard programming
* interface.
*
* #GtkFileChooser allows for shortcuts to various places in the filesystem.
* In the default implementation these are displayed in the left pane. It
* may be a bit confusing at first that these shortcuts come from various
* sources and in various flavours, so lets explain the terminology here:
*
* - Bookmarks: are created by the user, by dragging folders from the
* right pane to the left pane, or by using the “Add”. Bookmarks
* can be renamed and deleted by the user.
*
* - Shortcuts: can be provided by the application. For example, a Paint
* program may want to add a shortcut for a Clipart folder. Shortcuts
* cannot be modified by the user.
*
* - Volumes: are provided by the underlying filesystem abstraction. They are
* the “roots” of the filesystem.
*
* # File Names and Encodings
*
* When the user is finished selecting files in a
* #GtkFileChooser, your program can get the selected names
* either as filenames or as URIs. For URIs, the normal escaping
* rules are applied if the URI contains non-ASCII characters.
* However, filenames are always returned in
* the character set specified by the
* `G_FILENAME_ENCODING` environment variable.
* Please see the GLib documentation for more details about this
* variable.
*
* This means that while you can pass the result of
* gtk_file_chooser_get_filename() to open() or fopen(),
* you may not be able to directly set it as the text of a
* #GtkLabel widget unless you convert it first to UTF-8,
* which all GTK+ widgets expect. You should use g_filename_to_utf8()
* to convert filenames into strings that can be passed to GTK+
* widgets.
*
* # Adding a Preview Widget
*
* You can add a custom preview widget to a file chooser and then
* get notification about when the preview needs to be updated.
* To install a preview widget, use
* gtk_file_chooser_set_preview_widget(). Then, connect to the
* #GtkFileChooser::update-preview signal to get notified when
* you need to update the contents of the preview.
*
* Your callback should use
* gtk_file_chooser_get_preview_filename() to see what needs
* previewing. Once you have generated the preview for the
* corresponding file, you must call
* gtk_file_chooser_set_preview_widget_active() with a boolean
* flag that indicates whether your callback could successfully
* generate a preview.
*
* ## Example: Using a Preview Widget ## {#gtkfilechooser-preview}
* |[<!-- language="C" -->
* {
* GtkImage *preview;
*
* ...
*
* preview = gtk_image_new ();
*
* gtk_file_chooser_set_preview_widget (my_file_chooser, preview);
* g_signal_connect (my_file_chooser, "update-preview",
* G_CALLBACK (update_preview_cb), preview);
* }
*
* static void
* update_preview_cb (GtkFileChooser *file_chooser, gpointer data)
* {
* GtkWidget *preview;
* char *filename;
* GdkPixbuf *pixbuf;
* gboolean have_preview;
*
* preview = GTK_WIDGET (data);
* filename = gtk_file_chooser_get_preview_filename (file_chooser);
*
* pixbuf = gdk_pixbuf_new_from_file_at_size (filename, 128, 128, NULL);
* have_preview = (pixbuf != NULL);
* g_free (filename);
*
* gtk_image_set_from_pixbuf (GTK_IMAGE (preview), pixbuf);
* if (pixbuf)
* g_object_unref (pixbuf);
*
* gtk_file_chooser_set_preview_widget_active (file_chooser, have_preview);
* }
* ]|
*
* # Adding Extra Widgets
*
* You can add extra widgets to a file chooser to provide options
* that are not present in the default design. For example, you
* can add a toggle button to give the user the option to open a
* file in read-only mode. You can use
* gtk_file_chooser_set_extra_widget() to insert additional
* widgets in a file chooser.
*
* An example for adding extra widgets:
* |[<!-- language="C" -->
*
* GtkWidget *toggle;
*
* ...
*
* toggle = gtk_check_button_new_with_label ("Open file read-only");
* gtk_widget_show (toggle);
* gtk_file_chooser_set_extra_widget (my_file_chooser, toggle);
* }
* ]|
*
* If you want to set more than one extra widget in the file
* chooser, you can a container such as a #GtkBox or a #GtkGrid
* and include your widgets in it. Then, set the container as
* the whole extra widget.

*
* Most applications just need to turn on the
