Add a KineticsDatabase.reconstructKineticsFromSource function

This function reconstructs the kinetics from the
source data dictionary... this function is a little redundent
but allows us to double check that we can actually reconstruct
the kinetics from an rmg job, and also allows
modifcation of the source dictionary to get new kinetics
with high flexibility
