Encourage Planetary Growth for 2.7.1
Restores the "Encourage Planetary Growth" decision that was removed in the 2.7.1 "Wells" update. Paradox simply hid the decision from the menu rather than removing the triggers. This mod restores the decision to the menu and also allows Lithoids/Gestalt to use an identical planetary decision for 1000 minerals.
Also restores the population growth edicts for all empire types.
Works with Stellaris 2.7.1 and higher.
