Fixes to add compatibility with ProbeControlRoom and RealChutes 1.2

Hi SirHaxington, I've made some bug fixes to your excellent mod.

Unfortunately you seem to have disappeared from the face of Kerbin, but I will continue fixing bugs in your code. So far I've fixed two, and everything seem to be in good working order in 0.25. 

I Hope you'll come back to the KSP community!
