SOI changes are not detected about ksptrajectories

I already tried to implement this using the KSP solver. However, I didn't find a way to make it solve SOI intersection on an orbit that is not the current vessel orbit. So, unless someone knows how to do it, I think the only solution is to implement our own intersection algorithm. I don't know if there is an easy analytical solution, or if we'll need to search incrementally (maybe with a dichotomic search to refine the intersection point).

Edit: this is for intersections that happen after an aerobraking ; we can of course follow the flight plan that is already computed by KSP (including maneuver nodes) for the part that comes before the first atmospheric encounter.

feature implemented, but only before the first atmospheric encounter (following the stock KSP flight plan)
