Jet rebalance, DRE support, ATM support, better MFT integration.

Jet stuff is essentially what I gave you the other day, with the intake usage on the KA engines tweaked so they have a slightly higher operational ceiling.

DRE is split between Karbonite and Parts Pack, because it seemed to make sense to do it that way >_>

ATM is now enabled - separate file for PartsPack here too.

MFT/RF support is improved, but the KA tanks are not converted to MFT/RF since B9 users tell me MKS/OKS has issues with MFT, and MFT's TweakScale support is still not working.
