Reduces or eliminates staggering patterns due to cell-force imbalances

Improves stability and convergence of systems in which drag dominates
e.g. small particles in high-speed gas flow.

Additionally a new ddtPhiCorr strategy is included in which correction
is applied only where the phases are nearly pure.  This reduces
staggering patters near the free-surface of bubble-column simulations.

Allows the specification of a reference height, for example the height
of the free-surface in a VoF simulation, which reduces the range of p_rgh.

hRef is a uniformDimensionedScalarField specified via the constant/hRef
file, equivalent to the way in which g is specified, so that it can be
looked-up from the database.  For example see the constant/hRef file in
the DTCHull LTSInterFoam and interDyMFoam cases.

Disadvantage is that the BC values have to be specified in terms of hU
rather than U.  The alternative would be to add complex code to map h
and U BCs into the equivalent for hU.

The implementation now correspond to the definitions in the readily
available reference:

http://personalpages.manchester.ac.uk/staff/david.d.apsley/specturb.pdf

in which a large number of linear and non-linear models are presented in
a clean and consistent manner.  This has made re-implementation and
checking far easier than working from the original references which anyway
are no longer available for the LienCubicKE and ShihQuadraticKE models.
