tutorials/compressible/rhoPimpleFoam/les/pitzDaily: change from h to e to avoid instabilities from dp/dt
Also updated schemes and BCs

but currently assuming that the density needed to calculate the volumetric flux is "rho"

This provided greater accuracy and stability while MULES guarantees boundedness

simpleHarmonicMotion case removed temporarily pending the introduction of a suitable motion solver
