*_WEIGHTING values are things like food/shields/trade = 18/14/12 that give
a relative bias to some resources over others. Trade is always the lowest,
and generally food is more important than shields (if you grow you can get
more shields, but choosing shields in preference leads to stagnation).

This is complicated by the fact that food is not a static WEIGHTING, but 
amortized so it decreases in importance as the size of the food box grows
(which is another reason to boost it initially, and probably a bad thing 
to have done anyway). Thus, if you look carefully, the food formulas are
always optimized a little bit differently with cryptic comments to drive
you crazy if you don't understand this basic point.
