[ok] Infrastructure and Traffic growth refinements

[JumboShrimp]

If approx. 3,000 are to go up 2.5 levels until the end of the game, that would be 7,500 infrastructure upgrades in about 15,000 days, or one upgrade every other day, in GW2 (HaF) which is far behind in infrastructure upgrades.

The system is not really keeping up.  Looking at the 2 upgrades that took place in 12 days, that's one every 6 days, or only 1/3 of the needed pace.

Looks like we have 3 infrastructure starts in approx. a month, while we need 15 per month, so the pace needs to be 5x of the current rate in GW2 / HaF, since this GW is so far behind.
