1) New skewCorrectedSnGrad for non-orthogonal and skewness corrector
2) New freeSurfacePressure and freeSurfacePressure working with
   interfaceTrackingFvMesh
3) New interfaceTrackingFvMesh

- makes the intent clearer and avoids the need for additional
  constructor casting. Eg,

      labelList(10, Zero)    vs.  labelList(10, 0)
      scalarField(10, Zero)  vs.  scalarField(10, scalar(0))
      vectorField(10, Zero)  vs.  vectorField(10, vector::zero)

- makes for clearer code

ENH: make writeIfDifferent part of Ostream

fvPatchFields: Constructors from dictionary now call the corresponding constructor of the fvPatchField base-class
to ensure 'patchType' is set as specified.

Required substantial change to the organization of the reading of the
'value' entry requiring careful testing and there may be some residual
issues remaining.  Please report any problems with the reading and
initialization of patch fields.

Resolves bug-report http://bugs.openfoam.org/view.php?id=2266

for consistency with prghPressureFvPatchScalarField

prghPressure: New pressure BC to allow the specification of a fixed static-pressure distribution in the p_rgh field

Multiphase: Update all solvers to accommodate the split between twoPhaseMixture and incompressibleTwoPhaseMixture
