Update instructions for updating Header Tags SEO version 3.1.7 to

1) Make the needed database changes using the following:

DROP TABLE IF EXISTS headertags_silo;
CREATE TABLE headertags_silo (
 category_id int NOT NULL DEFAULT '0',
 box_heading VARCHAR (60) NOT NULL,
 is_disabled TINYINT (1) DEFAULT 0 NOT NULL,
 max_links int DEFAULT '6' NOT NULL,
 sorton TINYINT (2) DEFAULT 0 NOT NULL,
 language_id int DEFAULT '1' NOT NULL,
 PRIMARY KEY ( category_id, language_id )
);

INSERT INTO configuration (configuration_id, configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, set_function, date_added, use_function)
 VALUES (NULL,'Display Silo Links', 'HEADER_TAGS_DISPLAY_SILO_BOX', 'false', 'Display a box displaying links based on the settings in Silo Control<br>(true=on false=off)', '543', '20', 'tep_cfg_select_option(array(\'true\', \'false\'), ', now(), NULL);
