thermo: Standardise property names and remove molar functions

All property functions in the low-level templated thermo property
implementations and the high-level virtual interfaces have been made
consistent. All energies and enthalpies are lower case to denote that
they are specific quantities. Molar functions have been removed as these
are no longer used anywhere.
