[16.0][ADD] pos_hide_receipt_line

[adasatorres]

Good morning, this add-on allows you to hide product lines on the point of sale receipt, as long as the line's price is 0.

To do this, go to the product in the backend and enable the Hide Receipt Line field, which is only visible if the product is available in the point of sale. After that, simply go to the point of sale and create a line with the product at a price of 0.
