Pop Growth per Pop (pre 4.0)

Note: this should work on the last version before 4.0, but the changes in 4.0 make it obsolete.

Are you tired of the base +3.0 pop growth per colony?
Me too. So I removed it!

What does this mod do?
Pop growth on a colony starts out at 0.2 (yes, that is tiny). Pop growth increases more or less linearly with the number of pops. So, a colony with 10 pops will have around 2.0 pop growth. This effect is effectively uncapped until you reach significant overcrowding, I assume your pops will not stop growing if they can easily migrate to other planets.
To facilitate this, I also heavily amped the migration system. In particular, very small colonies get more immigration, and overcrowding and unemployment can quickly cause all popgrowth to migrate elsewhere. The auto-resettlement of unemployed pops has been sped up as well.
I did also add some scaling replicator jobs to Machine Empires to help them keep up.

What did I want to accomplish with this?
I wanted to remove the pop growth benefit that having lots of different colonies gives you. I feel like this caused some weird gameplay effects:
• Colonizing low habitability worlds just for the base pop growth.
• Two size 10 planets being more valuable than one size 25 planet.
• Building feeder habitats for the growth rate instead of the living space. (Less of a problem recently)
• Artificial “feeder worlds” with an optimized number of pops to keep the pop growth maximized, and let the resulting pops migrate elsewhere.

Instructions:
Install mod as usual.

!Very Important!:

* Only works in a new game!
* Upon starting a new game, either hit “Reset to Default” or jiggle the slider for “Logistic Growth Scaling”. If it says “10000” you are good.

Additional notes:
• How fast the galactic population grows is mainly dependent on how many empires you start with.
• I did not alter “growth required scaling” in any way, so make sure to tweak that if you want more or less pop growth in the late game.
