wpdb::escape is deprecated since 3.6

Hi,

I’m using your nice plugin with WordPress 3.6

I get the following notice when using WordPress in debug mode.

Notice: wpdb::escape est déprécié depuis la version 3.6! Utilisez wpdb::prepare() or esc_sql() à la place. in /var/www/webanalyse/wp-includes/functions.php on line 2871

I searched for escape in the plugin files and the hits are :

ad-integration.php (4 hits)
Line 2390: $sql = "INSERT INTO $table_name (user_login, failed_login_time) VALUES ('" . $wpdb->escape($username)."'," . time() . ")";
Line 2408: $sql = "SELECT count(*) AS count from $table_name WHERE user_login = '".$wpdb->escape($username)."' AND failed_login_time >= $time";
Line 2429: $sql .= " OR user_login = '".$wpdb->escape($username)."'";
Line 2447: $sql = "SELECT max(failed_login_time) FROM $table_name WHERE user_login = '".$wpdb->escape($username)."'";

Note for other users : this does not seem to have any effect on functionality. If you see this warning, this means you’re in debug mode, and you shouldn’t if you’re not actively developping your site.

Thanks !
