Fixed some bugs of trigger codes for French focuses
Added some cores for AI Russia

Optimized the code for the big event and fixed some potential crash-inducing code.
Replaced some event pictures and focus icons.

Fixed a bug of hiding event (misspelling caused duplicate triggers)

Fixed a bug about a trigger (the removal conditions of the national spirit of the French Civil War still judged the tags of Ositania and Brittany)

ADDED CUSTOM PATH RULES for the Netherlands, Poland, France, Yugoslavia, and China

Renewed the GDP icons (the symbols δ,ε,μ,Σ and Ω represent very small, small, medium, large, and very large respectively), added a law group and four laws (International Recognition, Import Policy, Fiscal Expenditure, Welfare Policy), and added related economic buffs for Canada, Japan, and China.

The French Civil War no longer uses the tags of Brittany and Occitania.

Adjusted some debuffs and outcomes of the European Spring.

For balance purposes, added two buffs at the start of the game for Germany (if future German content is released, buffs will be adjusted according to German strength).

Fixed some bugs.

Fixed a bug that Palestinian intervention in the Arab Civil War led to the direct annexation of Assad Syria

Fixed a bug that France was unable to complete subsequent focus due to Benin's independence
