WC_Cart::check_customer_coupons() public WC 1.0

Check for user coupons (now that we have billing email). If a coupon is invalid, add an error.

Checks two types of coupons:

1. Where a list of customer emails are set (limits coupon usage to those defined).
2. Where a usage_limit_per_user is set (limits coupon usage to a number based on user ID and email).
