Update Cart Quantity

This is not a module, but rather, changes to the core files.

Modification to display add and subtract images next to each product in the cart block.  This allows users to increase or decrease product quantities without having to navigate to the order summary page.

This modification is designed to work only with the default prestashop theme, using prestashop version 1.4.

In order to use this modification with other themes, may require altering your custom theme files.  Please contact me directly to confirm it will work with your theme before making a purchase.
