! Performance Optimization Submod:False Megastructures

A Self-use performance optimization submod. What to do: Define a false megastructure,to prevent AI's idle constructor ships to daydreaming how they can build so many megastructure. Lower "resource_table.megastructures.cost". More efficient when using many megastructure mod(Like Gigastructural Engineering & More + Planetary Diversity). May very slightly weakened AI because idle constructor ships may be locked when they need to do something. Compatibility: May cause some megastructure which factor really low can never be build.(But I don't think this will cause any issue.) Load order: Everywhere. Caution: Don't use this mod when you don't use any megastructure mod! It slows things down!
