Title: Introduce action hooks at the top and bottom of the coupon add/edit

At the moment there is no way for other plugins to hook in and add their own form inputs to the coupon add/edit screen.

I'd like to be able to do this for the AffiliateWP integration for WP-e-Commerce for our affiliate coupon tracking feature.
