Template cases: apply entrainmentPressure BC for p at outlet patches

Browse Source 
The boundary condition applied to pressure at open boundaries and outlets is switched
from totalPressure to entrainmentPressure. The latter boundary condition is more robust
since it calculates the pressure for inflow using (velocity) fluxes rather than velocity
on the patch.
