Additions in OpenCart 1.4.9.5

OpenCart 1.4.9.5. 1) Create the voucher like it is in OC 1.5.x 2) The same with checkout , in one page and the ability to use coupon/voucher. In case we use new address, autocomplete will be used in the fields. 3) Add an option (colors) in products instead of creating it each time we add a product. Part of it is already created but it can't be added in cart. Along with the fields already used in options tab, the color field will be added.
