add note to order

we need to be able to add NOTES to an order (similar to attaching notes to a product) but this NOTE should apply to the whole order.

ALL notes should print on the KOT but NOT on receipt

its a common feature in most POS systems

often when taking a Takeaway order we note the customers Name or maybe a description to help the server find the person when the order is ready.

Or it could be a NOTE for the chefs
