[1.10.x] Near Future Technologies (All 1.10, NFA returns)

I'm almost positive that RP-1 isn't more expensive than Hydrolox; not only are the production processes for Hydrogen much less efficient and uncommon. But while RP-1 doesn't require too much special storage (If i recall the tankage must be a certain standard to prevent contamination, but that's with most everything for a rocket). The infrastructure to support Hydrolox requires much more setup, and operation is subject to a constant energy cost. But in all honesty; depending on CKAN isn't a good idea in general. There's a slew of issues it brings, and while i can understand using it to get your feet wet with KSP modding i feel like you're well past that point. That's besides the point though; especially since the Author himself said he'd get back to you in time. In the meantime however; most of your desired changes could easily be accomplished with some custom Module Manager patches if you wanted to dabble with that. The modding subfourm would be more than happy to help instruct you on how to make them, it wouldn't be too hard to reduce the cost of LOX/HydroLOX for instance. And you could easily add back in engines/tweak their cost (Though if they were hard-deprecated you'd need to grab their models from the last version that had them). Then you could use a mod like Janitor's closet to remove anything you thought "Redundant", and as a bonus save a bit of RAM while doing so!
