The file amgparallelhelpers.hh included the amgbackend.hh
(via box/properties.hh) which in turn also includes amgparallelhelpers.hh

Replace the phaseIdx argument for the
porousDiffCoeff() function.

Feature/air gas viscosity new implementation

Closes #333

See merge request !223

The functions porousDiffCoeff() and diffusionCoefficient() are replaced
by porousDiffCoeff(phaseIdx, compIdx) and diffCoeff(phaseIdx, compIdx)

* Added new property type TauTortuosity
