multiphaseEulerFoam: Added switches to revert to the previous phase limiters for testing

Browse Source 
Optional switches "splitPhaseFlux" and "meanFluxReference" are now provided and
can be set true in fvSolution e.g.

solvers
{
    "alpha.*"
    {
        nAlphaCorr      1;
        nAlphaSubCycles 2;

        splitPhaseFlux  true;
        meanFluxReference true;
    }
.

.

to reinstate the previous form of phase flux limiters in which the mean and
phase flux differences are interpolated separately and the limited correction
referenced to the mean rather than phase flux.  This form of discretisation and
limiting is more aggressive than the latest version and hence less accurate but
it is hoped that the latest form of limitSum will handle the boundedness at the
upper limit reliably allowing the new more accurate limiters to be used for most
if not all multiphase simulations.
