合作社优化：中央计划委员会/National Planning Commission
Improve the worker-cooperative production method in game:
1. All workers can share the dividend, not only laborers, farmers and machinists in default settings.
2. The committee unlocks a new institution "National Planning Commission", which derives investment from all pops at 10% per level. This institution requires admin power like others. It can control the investment and consumption of all the society, just like the same institutions in our world.
