POS UI Extensions 1.7 Update: Support for multiple cart discounts

As of March 13, we added the following updates to POS UI Extensions:

• Added a discounts property to the Cart object, which includes all cart discounts.
• Added addCartCodeDiscount to the Cart API, which allows the UI extension to add a code discount. The existing applyCartDiscount will still function for code discounts, too.
• Added remove AllDiscounts to the Cart API, which allows the UI extension to remove all cart discounts.
• Added a listHeaderComponent to the List component.

All of the changes are available for POS UI extensions version 1.7.0 and POS app version 9.4.0. See the version log for all version details.
