Changes the default when ordering an item via MiniVend to allowing multiple
lines on the order form for each item. The default, No, puts all orders with the same part number on the same line.
Setting SeparateItems to Yes allows the item attributes to be easily set for different instances of the
same part number, allowing easy setting of things such as size or color.
SeparateItems Yes
Can be overridden with the mv_separate_items variables (both scratch and values).
