A rounding problem with population

Well, it only counts in 10s, it's not exactly rounding. The pop is actually counted in memory as 60, and is not increasing by 1, or even .5 and therefor won't go up. You'd need about 850 pop to get it to grow even with G3, it looks like.

But it *IS* rounding--the fraction is being rounded down to zero as the field can't hold it.

I think this should be special-cased: If the growth rate is positive the population should grow by at least the minimum possible amount.

Note that this would also address LA Ermor, LA R'yleh and Hinnom depleted provinces.
