At the specie level:
hs = sensible enthalpy
ha = absolute (what was total) enthalpy
es = sensibly internal energy
ea = absolute (what was total) internal energy
At top-level
Rename total enthalpy h -> ha
Rename sensible enthalpy hs -> h
Combined h, hs, e and es thermo packages into a single structure.
Thermo packages now provide "he" function which may return either enthalpy or
internal energy, sensible or absolute according to the run-time selected form
alphaEff now returns the effective diffusivity for the particular energy which
the thermodynamics package is selected to solve for.
