* Now when picking up max. stack amount is checked.
* Added cInventory::AddItemAnyAmount() which will not fail if it cannot add all items (it will just modify amount)
* If there is no space in inventory and picking up stacked items, it will try to fill stacks already in inventory, partially picking up the item.
* When closing inventory player will drop any items it's currently 'dragging'
