Release new version 1.8.9

* This Maintenance update has 2 code tweaks for compatibility with themes and plugins that load images via the wp_kses_post sanitizer as WooCommerce does since version 3.4.0 with widgets and on Cart page.
* Tweak - Append lazy attributes to attribute list of allowed post tags list so that lazy load can run on frontend when that content is output via wp_kses_post
* Tweak - Add noscript tag to allowed post tags list to resolve duplicate image if that image is output via wp_kses_post
* Tweak - Test for compatibility with WooCommerce version 3.4.1
