Enables the ability to use standard WooCommerce fixed-product and percent coupons with recurring WooCommerce subscriptions.

New field for allowing coupons to be enabled with subscriptions
If you have a WooCommerce store that has a mix of products and subscription offerings, you may have noticed the frustration of providing coupons and discounts and to your customers.
Historically, you would need to create 2 different coupons each for products and for subscriptions. Customers would then need to apply multiple coupons to their cart in order for discounts to be applied to the initial cart total as well as recurring cart totals.
But no more!
Better Recurring Coupons allows you to use a single standard coupon for both normal products and subscriptions.
