Changed the removal of Public Relations to be save-game compatible.

Adjusted naturalists spawns from 2 to 1, since the AI would flood the map with these instead of using them. Only finding the spot for 1 National Park should be doable for most AI empires.

Removed Public relations resolution since it was too boring and mostly didn't do anything.

Tweaked when some resolutions were available. Mainly toned down the late-game eras to only let the victory-related or counter-victory-related resolutions come up.

Changed World Religion from +50 to +30, since the game is hardcoded to also add this effect to warrior monks, which was way too powerful at +50.
At +30 this is still powerful for both Apostles and Warrior Monks, but it shouldn't feel like cheating with the Warrior Monks razing cities left and right.

Fixed some spelling.
