Not save-game compatible!

Fixed a bug where some city-states suddenly may own more than one city.. and..

Well the establishing of a sphere of influence is now related to the City-State's original capital not any city.

I increased the Delegate count of getting Global Hegemony by +6. It's not a lot when you are in a huge map, but it makes a big difference in small maps as it means you have to look toward "expanding" or getting votes.
I rescaled the Population Threshold per era from 40-60, so civs who really get ahead can find themselves losing a delegate or two when they advance to the next era. This allows slower civs to stay ahead in the delegation game in terms of population.
I did some renaming, but nothing too big.

General Changes
Each 40 Population now increases unhappiness by +1% not by +2%. (This nerfed wide empires too much!)
Fixed a bug where Spacefight Regulations, Project TEMPEST, and XCOM Initiatives could be circumvented by upgrading units to their XCOM, GDR, Stealth Bomber, and Jet Fighters counterpart.
Open Door Policy on a City-State prevents bullying(Mongolia can't force annex!)
Decolonization repeals all Sphere of Influence of the person as well as reducing influence of all non-allied city-states.

Future Changes
Sphere of Influence are now unrepealable (Broken until later VP version release).
Open Door Policy on a City-State now prevents Venice from buying the city-state(Broken until later VP version release).
