Matthias Clasen 3923ba1605 Avoid overlong file chooser buttons 
When bookmarks are long, the file chooser button would
grow too much. This can be avoided by ellipsizing.

/**
* SECTION:gtkfilechooserbutton
* @Short_description: A button to launch a file selection dialog
* @Title: GtkFileChooserButton
* @See_also:#GtkFileChooserDialog
*
* The #GtkFileChooserButton is a widget that lets the user select a
* file. It implements the #GtkFileChooser interface. Visually, it is a
* file name with a button to bring up a #GtkFileChooserDialog.
* The user can then use that dialog to change the file associated with
* that button. This widget does not support setting the
* #GtkFileChooser:select-multiple property to %TRUE.
*
* <example>
* <title>Create a button to let the user select a file in /etc</title>
* <programlisting>
* {
* GtkWidget *button;
*
* button = gtk_file_chooser_button_new (_("Select a file"),
* GTK_FILE_CHOOSER_ACTION_OPEN);
* gtk_file_chooser_set_current_folder (GTK_FILE_CHOOSER (button),
* "/etc");
* }
* </programlisting>
* </example>
*
* The #GtkFileChooserButton supports the #GtkFileChooserAction<!-- -->s
* %GTK_FILE_CHOOSER_ACTION_OPEN and %GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER.
*
* <important>
* The #GtkFileChooserButton will ellipsize the label,
* and will thus request little horizontal space. To give the button
* more space, you should call gtk_widget_get_preferred_size(),
* gtk_file_chooser_button_set_width_chars(), or pack the button in
* such a way that other interface elements give space to the widget.
* </important>
