fvOption::radiation: New fvOption providing the radiation source to the energy equation

Browse Source 
Radiative heat transfer may now be added to any solver in which an energy
equation is solved at run-time rather than having to change the solver code.

For example, radiative heat transfer is now enabled in the SandiaD_LTS
reactingFoam tutorial by providing a constant/fvOptions file containing

radiation
{
    type            radiation;
    libs ("libradiationModels.so");
}

and appropriate settings in the constant/radiationProperties file.
