fluidThermophysicalTransportModel: Removed alphaEff from the public interface

Browse Source 
alphaEff is now an internal field used only for the implicit energy correction
term, kappaEff, q and divq are the general and rational interface to thermal
transport.

XiFoam and PDRFoam now explicitly instantiate a unityLewisEddyDiffusivity
fluidThermophysicalTransportModel as the the unity Lewis number approximation is
hard-coded into the formulation of the energy/composition system.
