Operator-splitting is used for the diffusion

Thermodynamics and sub-models:  Removed "Sp" boundedness corrections on transport, replaced with "bounded Gauss" scheme

so that the effect of the term on the enthalpy equation is optional

phaseModelTable superseded by PtrDictionary

multiphase and fireFoam: set phi based on the interpolated U before the pEqn construction for the p BCs

Required the addition of the divDevRhoR function to all incompressible turbulence models

compressibleTwoPhaseEulerFoam/pEqn.H: Corrected handling of the kinetic theory drag in the pressure equation

Also improved the efficiency of the handling of the models by evaluating only those specified.
