Merged requested to merge Scinopode/ogs:Effective_thermal_conductivity_volume_fraction into master
The property 'EffectiveThermalConductivityPorosityMixing' was limited to two-phase media (liquid+solid). This MR generalises the property to two-phase or three-phase media (gaseous+liquid+solid or gaseous+solid or liquid+solid). The name should actually be changed to something like 'EffectiveThermalConductivityVolumeFraction', but that would require a change of all input files and would thus endanger backward compatibility.
