add fresh workflow: enter different weight than ordered

[fsmanuel]

At the moment we can only add the exact amount to the bill based on the price of a product and quantity of that product that it has ordered.
We want to sell vegetables and fruits, and later also other products we will sell without packages with fixed weight. The issue is that it is not possible to get the exact weight as ordered because carrots or pumpkins are never the same size/weight.

Solution proposal:
with products (like veggies/fruit) sold per kg without fixed quantity packaging, add functionality that the person dividing the veggies/fruit can enter the amount of a product that he/she has allocated to a certain member and the system ignores the ordered quantity.
to do this we have to separate the amount ordered from the amount you get and pay
also the system has to accept irrational numbers (e.g. 0.8 kg, 3,67 kg).

the amount ordered by the member is then an indication to allocate a certain amount of the amount that is delivered of that product to that member. the member who divides the veggies has to see what is ordered, puts an amount of the right veggies on the scale until it is near what the ordering member has ordered.
