OpenFOAM 5.0 thermo changes, effect on chemkin

Related to a few other posts on my adventures updating OpenFOAM, I've noticed that the chemFoam gri tutorial now has a lower maximum temperature by about 40 K. With the new mass based thermophysics, chemkinToFoam now appears to be mandatory to run. Seems like this change has caused quite a bit of changes that haven't been signaled...

I can confirm that the change happens in the transition from 4.1 to 5.0, as the 4.1 version of chemFoam has better agreement. This doesn't bode well for the future...
