Add a note to an item

This feature let you edit the title of an order's item.
In order to activate this feature, you need to check the option into Config, Items page.
During an order, it will then be possible to double click on an item, directly on the receipt, in order to be able to edit it and add precisions.
This operation will only modify the title of the item, in this particular order, but will not change the price of the item.
This feature is meant for taking notes on a particular item (for example : pizza without mushrooms).
