Scalability Pro 6.18

* Added new WP All Export optimisation for when editing exports to speed up or avoid the wp_postmeta scan to grab all postmeta keys
* Added preview and customizer check for "Remove OR check for private items on front end" optimisation

* Added full namespacing for plugin update checker to prevent conflicts with 3rd party plugins

* Merged stop-phone-home functionality including fixes for paypal & stripe

* Rollback to 5.94 + bug fixes added from other feature branch (but other major new features and implementation pattern removed for further testing)

* Fixed bug with admin notice for term filtering where if you ran the rebuild from the GUI, it kept telling you it was in progress (term rebuild required to clear the notice though)
