Original code:
std::min(std::pow(0.8f, dis_item.damage), 1.0);
results in compile error with msvc.

Then, I edit it to
std::min(std::pow(0.8f, dis_item.damage), 1.0f);
then in Visual Studio, the code passes to build.
But in GCC, there is a compile error.

Finally, I edit it to
(float)(std::min(std::pow(0.8, dis_item.damage), 1.0))

passing 0 produces a std::logic_error: 'basic_string::_S_construct null not valid'

… of that type already in the player's inventory when calculating the projected volume.

Adds a helper function in the pickup class that changes the projected volume depending on whether the item is stackable or not and if any of that item is in the player's inventory.

Add a position field in struct pickup_count; this field is used by Pickup::pick_up to keep track of the position of the item in the copy of the player's inventory.
