Always return void to avoid various bugs associated with automatic
type conversion.

reactionThermo/functionObjects/moleFractions/moleFractions: New functionObject to calculate and write mole-fraction fields

    This function object calculates mole-fraction fields from the mass-fraction
    fields of the psi/rhoReactionThermo and caches them for output and further
    post-processing.

    The names of the mole-fraction fields are obtained from the corresponding
    mass-fraction fields prepended by "X_"

    Example of function object specification:

        moleFractions
        {
            type psiReactionThermoMoleFractions;
        }

     or

        moleFractions
        {
            type rhoReactionThermoMoleFractions;
        }

    depending on the thermodynamics package used in the solver.

The c++0x is used rather than c++11 to support gcc-4.5.?

etc/config/paraview.*: Update include directory name which is 3.0 rather than 4.0 even for ParaView-4

temperatureDependentAlphaContactAngleFvPatchScalarField: Temperature-dependent constant alphaContactAngle scalar boundary condition

Evaluates the contact angle as a function of the optionally specified
temperature field (defaults to T).  The "theta0" function is provided as
a DataEntry currently supporting:
    CompatibilityConstant
    constant
    csvFile
    polynomial
    table
    tableFile

for consistency with prghPressureFvPatchScalarField

Corrected rho name specification.

It is not clear what form an fvOptions source should take as f is not a
transported dynamic field. For the moment the fvOptions source from the
f-equation has been removed until there is a specific need which will
show what the form should be.
