-- AD Chain Run (kædens handlinger i spillet)
-- Udfører ADChain's plan: skifter frie marker (kun "auto", højst MAX_FIELD_SWITCHES pr. tick), tænder/slukker
-- mellemled, opretter manglende forsyningsflows (højst MAX_NEW_FLOWS pr. tick) og stopper flows for rødder der
-- er slået fra. Hver del kører i pcall, så en fejl ikke stopper resten. Spilkald kun inde i funktioner.
