Reverted mod to a smaller change.

Now it just give +1 charge for AI Emperor and +2 charge for AI Immortal.

After playing a few games and seeing that the AI goes crazy for luxuries in later industrial and modern era. I did test to not have corporation and industry mode on, but this time I switched off the latest frontier pack completly, that did the trick. AI works normally with luxuries again. I also tested the mod with diffrent yields and the pack enabled and the AI is better just with the extra charges so lowered the improvement pseudoyield from 4 to 2 (Double Standard) and remove other pseudoyields.

First version
