fvModels: Specify source property values in field files

Browse Source 
When an fvModel source introduces fluid into a simulation it should also
create a corresponding source term for all properties transported into
the domain by that injection. The source is, effectively, an alternative
form of inlet boundary, on which all transported properties need an
inlet value specified.

These values are now specified in the property field files. The
following is an example of a 0/U file in which the velocity of fluid
introduced by a fvModel source called "injection1" is set to a fixed
value of (-1 0 0):

    dimensions      [0 1 -1 0 0 0 0];

    internalField   uniform (0 0 0);

    boundaryField
    {
        #includeEtc "caseDicts/setConstraintTypes"

        wall
        {
            type            noSlip;
        }

        atmosphere
        {
            type            pressureInletOutletVelocity;
            value           $internalField;
        }
    }

    // *** NEW ***
    sources
    {
        injection1
        {
            type            uniformFixedValue;
            uniformValue    (-1 0 0);
        }
    }

And the following entry in the 0/k file specifies the turbulent kinetic
energy introduced as a fraction of the mean flow kinetic energy:

    sources
    {
        injection1
        {
            type            turbulentIntensityKineticEnergy;
            intensity       0.05;
        }
    }

The specification is directly analogous to boundary conditions. The
conditions are run-time selectable and can be concisely implemented.
They can access each other and be inter-dependent (e.g., the above,
where turbulent kinetic energy depends on velocity). The syntax keeps
field data localised and makes the source model (e.g., massSource,
volumeSource, ...) specification independent from what other models and
fields are present in the simulation. The 'fieldValues' entry previously
required by source models is now no longer required.

If source values need specifying and no source condition has been
supplied in the relevant field file then an error will be generated.
This error is similar to that generated for missing boundary conditions.
This replaces the behaviour where sources such as these would introduce
a value of zero, either silently or with a warning. This is now
considered unacceptable. Zero might be a tolerable default for certain
fields (U, k), but is wholly inappropriate for others (T, epsilon, rho).

This change additionally makes it possible to inject fluid into a
multicomponent solver with a specified temperature. Previously, it was
not possible to do this as there was no means of evaluating the energy
of fluid with the injected composition.
