changed the way of refreshing a page after batch adding products to the cart (because earlier, in rare cases, with some web server configurations, the page could be completely reloaded with all resources)
the special function for disabling forms (setting sort priority for columns of attribute groups and the filter settings) has been converted to an option and improvements have been made related to this
added option to enable all attributes at once in the filter block (for convenience when there are a lot of attributes)
minor improvements to tooltips in the module settings forms
