Also credits go to Tehlikelierd as he sent some of the files from the first cargo stack mod that was here and for help with figuring out how to make the mod work

Note, this is the first mod ive made and im basically completely new to this world, hoped to get a multiplication on all types of income, but dont think i found all the possible places for that, so i only managed to dig my way to cargo delivery payment
