[CR] Removed penalties and base cost when calculating obtain_cost() for wielded item

[Raschert0]

Summary

SUMMARY: Balance "Reloading wielded items now costs less than reloading items in inventory"

Purpose of change

I found, that obtain_cost() call (i.e., when reloading something) returns the same value both for wielded and for stored in inventory items. Maybe this is intended, but it isn't looking like that

Describe the solution

So, when obtain_cost() is called for item, whose owner (who) is_armed() and has this item (target()) as weapon, we calculate item_handling_cost() without penalties (like it is done for holsters) and with zero base_cost (because item is already in hands)

Describe alternatives you've considered

Maybe there can be non-zero base_cost or something else, but I don't think that I know how to do it in another way
