Member function dKcdTbyKc in thermo.H is calculated from S and G at Pstd.
Thus dGdT was removed from the thermos.

- Add optional hRef, eRef and Tref as optional.

- Use new thermo to multiphase solver icoReactingMuliPhaseFoam

- Remove hRefConst and eRefConst thermos.

TUT: Updated tutorials

- deprecated Feb-2018, but not marked as such.

  The set() method originally enforce an additional run-time check
  (Fatal if pointer was already set), but this was rarely used.
  In fact, the set() method was invariably used in constructors
  where the pointer by definition was unset.

  Can now mark as deprecated to catch the last of these.
  We prefer reset() for similarity with std::unique_ptr

  Eg,
  FOAM_EXTRA_CXXFLAGS="-DFoam_autoPtr_deprecate_setMethod"  wmake

- reduces the number of files, eases code refactoring

Reduce the number of phaseSystems libraries:

- phaseSystems previously had a number of smaller libraries to provide
  interface and model properties, etc. This potential flexibility was
  never actually used anywhere, but causes cyclic dependencies between
  phaseSystem and the models (and turbulence) that causes extreme
  difficulty for mingw linking (issue #1238).

- libincompressibleMultiphaseSystems
  - removed: libmassTransferModels

- libmultiphaseSystem
  - removed: libcompressibleMultiphaseEulerianInterfacialModels

- libreactingMultiphaseSystem
  - removed: libreactingPhaseSystem
  - removed: libreactingEulerianFvPatchFields
  - removed: libreactingEulerianInterfacialCompositionModels
  - removed: libreactingEulerianInterfacialModels
  - removed: libmultiphaseReactingTurbulenceModels

- libreactingTwoPhaseSystem
  - removed: libreactingPhaseSystem
  - removed: libreactingEulerianFvPatchFields
  - removed: libreactingEulerianInterfacialCompositionModels
  - removed: libreactingEulerianInterfacialModels

Avoid duplicate symbol for phaseCompressibleTurbulenceModels

  Common turbulence models are defined in libreactingMultiphaseSystem,
  and libmultiphaseReactingTurbulenceModels is now redundant.

  The libtwoPhaseReactingTurbulenceModels extends the common models
  for reactingTwoPhaseSystem.

- prelude to code refactoring
