freezer and cooler ice slots

[JohnVerv]

Freezer produces ice, but also should have one slot that collects ice, if the freezer loses power it will still keep contens frozen\cool but with a spoil rate between a fridge and powered freezer;
Also a portable cooler box with ice slot that can be used to transport food items and fish, as long as there is ice in the cooler slot, contents will spoil at a reduced rate
Perhaps also ice melting relative to ambient temps (eg ice melts more slowly in the snow maps compared to the desert maps)
