interPhaseChangeFoam: No need to check continuity error and the velocity divergence defines the compressibility effect

compressibleTwoPhaseEulerFoam: Improved handling of compressibility effect on continuity and boundedness

Operator-splitting is used for the diffusion

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phaseModelTable superseded by PtrDictionary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
