Subject: [PATCH] Variable product ajax_add_to_cart fix.

Ensure simple products still use the class ajax_add_to_cart but not have them interfere with Variable products. Fixes the issue where hitting "Select options" on a variable product from the archive-product.php template adds them straight to cart.
