Fixed winter dynamics- though still highly simplified survivorship.

All bees during the winter are now house bees, not nurse, so graphs should look a tiny bit better. 

The issues that remain are:
In the second season, the hive runs out of space, and this should be impossible with the caps I've imposed.  
Right now, honey and pollen storage are each capped at 1/4 of the vacant cells, leaving half the cells for the eggs- of which t here are never more than 2000. So can the hive get too full? 

The hive overflowing is causing the jagged appearance of the graphs.

There is still a SMALL amount of work to be done with the winter dynamics- it seems like not quite as many adult bees are surviving as we want? the hive collapses in early March (second one) and somehow recovers.  This also should be impossible. 

Closely related to this are issues with honey storage- if I remove the cap, it skyrockets, and it has weird jumps.
