* Feature: added new option "Show Item Code field" on menu Configuration - Preferences - Order - Order Buttons. With this option it's possible to show or hide Item Code field on Order window.
* Improvement: on menu Configuration - Preferences - Menu Items it was possible to specify item's width and height up to 200 pixels. Now we increased this size to 1000 pixels. This size is used to display items as buttons on Order window.
* Bug fixed: it was possible to remove item by pressing - (minus) and entering quantity like 1 for notified items even if "Can remove notified items" option was unchecked on on menu Configuration - Preferences - Order - Item Buttons.
