Fixed some localisations

Checked compatibility with 3.5 - Yes

Changes:

Notes: I found it that fleet power was always the correct choice as it's the mayority of diplo weights lategame.
I also found out that Unity from Power Projection is bugged and always gives the max value (actually 105%) no matter the Power projection %.
Peace Through Strength:
Diplomatic_weight from fleets reduced from 40% -> 20%.
+30 Unity from Power Projection gone.[\strike]
+10 Energy from Defensive Pacts.

Notes: Even with an Empire that focuses on allot of population, seemed a bit weak.
Open Door:
Diplomatic Weight from Pops increased from 40% -> 60%.
Removed +20 Society Research from Migration Pacts.
Added +15 Consumer Goods from Migration Pacts.

Ideological Authority: Overlord
Now visible even if you are not an overlord, just disabled.
No longer shows "Hidden Effect", but just tells you the modifier that it adds. (upps)
