Change to Unit Construction Costs

Unit construction costs are now more even. They were originally tied to increases in combat strength as the unit was built and since the unit strength increases were back loaded (a unit would get most of its strength in the last few turns before it was complete) units were costing a few pennies a day to build for the first 30 turns or so.
