Near Future Non-Engines

Updated all non-engine Near Future packs, not much to do, fixed some
fuels, etc.  Note that the Capsule command pod has broken internals ATM,
not something that can be fixed by RO (I don't think).

Starting in on the engines.  I think the guy who made it originally
confused kN with N, or was simply trying to match stock balance.  Either
way, got some nerfin' to do!
