- <code>$options = &drupal_static(__FUNCTION__);</code> instead of <code>$options = &drupal_static(__FUNCTION__, array());</code> in field_ui_field_type_options(), field_ui_widget_type_options(), field_ui_formatter_options()

- New code for field_ui_widget_type_options(), field_ui_formatter_options()
