WP Plugins Scalability Pro 5.24

* Added new detection of unnecessary GROUP BY when LIMIT 0,1 is being used
- this seems to happen in imports and causes a table scan of wp_posts, so this should result in a good boost for imports on large sites
* Added further improvement for 'defer term counting'
- when a new item is published, that post types cache is wiped
- this leads to slower imports since an entire recount can happen after every import
- The change has modified this query to fetch data from our own cache table which stores the counts for 24 hours if you enable the defer term counting option
* Added Optimize Product Attributes Lookup functionality to the Imports tab
- WooCommerce maintains the product attributes table EVEN IF you deselect to use it
- One outstanding issue here on larger sites is the SQL where they check WHERE product_id = 984353 OR product_or_parent_id = 984353;
- only the product_or_parent_id needs to be checked in this case and then an index gets used
- This functionality alters this SQL query if you enable the option on the Imports tab
