interFoam family: Added run-time selectable LTS support

LTS is selected by the ddt scheme e.g. in the
tutorials/multiphase/interFoam/ras/DTCHull case:

ddtSchemes
{
    default         localEuler rDeltaT;
}

LTSInterFoam is no longer needed now that interFoam includes LTS
support.

-Description
-    Solver for 2 incompressible, isothermal immiscible fluids using a VOF
-    (volume of fluid) phase-fraction based interface capturing approach.
-
-    The momentum and other fluid properties are of the "mixture" and a single
-    momentum equation is solved.
-
-    Turbulence modelling is generic, i.e.  laminar, RAS or LES may be selected.
-
-    For a two-fluid approach see twoPhaseEulerFoam.
