Alter HikaShop Cache

Applies caching for HikaShop category and product pages to significantly speed-up page load time.

Uses tagged-based approach: once a product is modified, all the pages with this product are refreshed. Same for categories.

• Cache is automatically refreshed on essential action which should affect the output: e.g. once a product badge or a discount is added to specific category of products.
• Caching of HikaShop "Categories listing" pages (list of products from category): exclude/include only specific categories and manufacturers, allow/disallow products page caching for specific usergroups, access levels and menu items.
• Caching of HikaShop "Product page" pages (individual product): exclude specific products from caching, allow/disallow product page caching for specific usergroups, access levels and menu items.
• Optional separate caches per usergroup and per access level.
