Coupon Email Invoice Addition| Feature Request

[NikKirstein]

EXPLANATION OF THE ISSUE

Feature Request: Display coupons used in email invoices.
This is important as currently, the discount table row displays the discount but not why it is there/what gave the discount. I attempted to do a work around with add_action or filters but it is so impossibly annoying to insert anything into the email template the way it is currently setup to display information based on each item in a list (be it $totals or $field). It seems quite easy to use the existing get_used_coupons function to display the coupons used underneath the discount words in the discount row or even insert a new row with coupons which is probably even easier but difficult as can be without modifying the core files instead of relying on add_action.

STEPS TO REPRODUCE THE ISSUE

1. Attempt to use add_action to add coupon codes to email invoices
2. Difficulty due to the way the email templates are setup.
3. Give up and make issue report.
