Comment 7 for bug 1767187

I inserted some printf to identify wares without preciousness, and I got many rows like:

Preciousness for Clay for atlanteans not defined in its init.lua file
Preciousness for Brick for atlanteans not defined in its init.lua file
Preciousness for Fruit for atlanteans not defined in its init.lua file
Preciousness for Honey for atlanteans not defined in its init.lua file
.....

So I understand why kInvalidWare is returned, only it is not reliable - sometime author forgets to insert entry for particular tribe and than it returns preciousness 254. We should somehow distinguish if ware is indeed invalid or just forgotten in init.lua files..
