Create BigReactors.cfg

This file goes along with bigreactors.zs . I like the Steam Turbine, but not the reactor. It's not really "nuclear". Here are the key settings:

    B:autoAddUranium=false

    # with a Gold coil, the best available in this pack (GT 5 removed all its cool blocks !!), Steam Turbine is 2x as efficient as RC steam engines, taking 40 mB/t and turning it into 16 MJ/t vs. RC's 8 MJ/t for the same steam
    D:powerProductionMultiplier=0.6

    # This disables power output from the Reactor
    B:enableCyaniteFromYelloriumRecipe=false
    B:enableReactorPowerTapRecipe=false

     # This makes using the reactor as a steam generator very, very expensive
    D:fuelUsageMultiplier=10.0
