Display discount_amount in cart page in PS 1.7.5.1

[MariusGi]

Hello,

I am trying to display total discount_amount which is set in backend bellow "specific prices" section.
The template I am looking at is cart-detailed-totals.tpl which is in themes/<theme_name>/templates/checkout/cart-detailed-totals.tpl

When I print $cart object there is a protected property list which I want to get.
For example discount_amount property. Then if there are more products I just to plan to loop and get total discount_amount for basket.

The goal is to show how much price is discounted as currently it shows only total AFTER discount.

Do you have any ideas how to solve it?
