Minor clean-up

Henry Weller authored 7 years ago and Andrew Heather committed 7 years ago

The combined solver includes the most advanced and general functionality from
each solver including:

    Continuous phase
    Lagrangian multiphase parcels
    Optional film
    Continuous and Lagrangian phase reactions
    Radiation
    Strong buoyancy force support by solving for p_rgh

The reactingParcelFoam and reactingParcelFilmFoam tutorials have been combined
and updated.

Revert changes in tutorial to correspond to the version in OpenFOAM-2.1.x

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.
