- cyclicACMIFvPatchField::updateCoeffs() now again redirects to
fvPatchField::updateCoeffs(const scalarField& weights);
- which redirects to fvPatchField::updateCoeffs();
- except on wall functions where the weights are used to switch off
  turbulence generation
- renamed the updateCoeffs on the fixedFluxPressure bc to updateSnGrad.
