Woocommerce Name your price 3.6.1

* Fix: Correctly update existing product in cart, instead of creating new product.
* Fix: More precise tax calculations when ordering again.

* New: Supports editing price in cart (by redirecting back to original product page)
* New: wc_nyp_price_input_attributes and wc_nyp_price_input_attributes filters.
* Fix: Resolve bug with multiple [product_page] shortcodes on same page (esp 1 variable, 1 simple ).
* Fix: Incorrect price when paying for failed subscription renewal in tax-inclusive mode.
Fix: Automatically hide Stripe request buttons for NYP products as they don't support custom prices.

* IMPORTANT: WooCommerce 3.1.0 is minimum required version. If you are running a WooCommerce version older than 3.1, you will not see any prompts to update Conditional Shipping and Payments from now on, and will need to install extension updates manually!
* IMPORTANT: PHP 5.6.20+ is now required.
* Update: Tested against WC 3.7
* Tweak: Improve variable product performance by passing $variation object to woocommerce_variation_is_visible callback.
