Displaying average cost of each inventory item

[lubos]

OK, added.

[16.3.50] Added "Average cost" column to "Inventory Items" tab

When viewing list of inventory items, Manager was displaying “Qty on hand” and “Value on hand” columns to show how many inventory items there are and what is their value. If one wanted to calculate average cost per unit, it would have to be done manually by dividing value and qty. The latest version will show new column “Average cost” which is useful to make sure selling price is above the acquisition cost.
