Support player's inventory, container and companion windows with dropping and picking up items from the world. Add ItemTransfer class to handle transfers similar to DragAndDrop. When a container window is opened the view is added to the set of targets and removed when closed. If ALT is pressed instead of starting dragging an item perform a transfer. If there is 1 target which is not a source move item there. If there is no target drop item into the world using WorldItemModel. Special case is picking up an item. Don't start dragging, just update the player's inventory view because the item is already there.
