Dropping boxes items at mouse location position

The idea is to change the drop-down location when the character drops the box (so that the item falls in the cell where the mouse was directed) - Now all items fall exclusively at the feet of the character, which creates a mess and difficulty to pick up the right item when throwing a few boxes.

As an alternative, when clicking in the inventory by right-clicking on the box, can make items  fall in random order near the character in a circle within 2-3 cells, so at least you can drop 4-5 boxes and only then change the coordinates of the character. 

For now you need to change character position on each box dropping, to avoid mess and pickup necessary item.
