Increase the maximum number of milk delivery tanks to 16


This is being looked into. Rejecting for now though.

15 is an odd number, those of us with OCD are triggered. Plus many of us have multiple farm hand jobs. I don't know about anyone else but I like to do four tanks a day from each dairy. 16 tanks would make this much easier while 15 throws it off by one. I understand the reason for not having 100's of tanks but I'd hope 1 more would not hurt and give us a nice even number of tanks to work with. Thanks
