#406 move inventory crashes when item doesn't exist in from_index slot

Commands.cpp:6552 need a item null check before item->details.item_locked

    else if(sep->arg[4][0] && strncasecmp("move", sep->arg[0], 4) == 0 && sep->IsNumber(1) && sep->IsNumber(2) && sep->IsNumber(3) && sep->IsNumber(4))
    {
        int16 from_index = atoi(sep->arg[1]);
        sint16 to_slot = atoi(sep->arg[2]);
        sint32 bag_id = atol(sep->arg[3]);
        int8 charges = atoi(sep->arg[4]);
        Item* item = client->GetPlayer()->item_list.GetItemFromIndex(from_index);

        if(item->details.item_locked)
        {
            client->SimpleMessage(CHANNEL_COLOR_RED, "You cannot move the item in use.");
            return;
        }

Fixed pending git update.
