Changelog:
v7.3 /
*Change versioning to 0.x.y internally.
*Only apply SF patch to parts with SolidFuel (less log spam)
*Fixed KIDS interoperabilty
*Fixed so that throttle and massMult work for CONFIGs that don't use techlevels.
*thrustCurves now modify heat in proportion to thrust
*Launch clamp refuel pumps default to off (note: the value is persistent, so if you have a saved craft from before this change, and it has clamps, they will still be defaulting to on).
*aristurtle: fix bugs in HGR config, fix KW typos, add more KW tanks, add KSO tanks
*Increase B9 spaceplane parts fuel capacity by 1.5x to bring them more in line with their physical volume, switch them to using Fuselage tank type
*Fix right-click menu displays regarding rated thrust; now there is only one display, and it only shows up when there is a thrustCurve in use.
