Display item message

When selecting an Item there can be messages/changes that the server needs to know about the product

often we have to put a note on a product to advise the server that we are out of Blueberries and instead we will be using Strawberries... or in the case of Soup we have to advise the servers that this item takes longer to prepare..

Ideally we need the ability to store a message against each item and display it in a popup when the item is selected
