solvers::incompressibleFluid: New solver module for incompressible fluid flow

Browse Source 
executed with foamRun for single region simulations of foamMultiRun for
multi-region simulations.  Replaces pimpleFoam, pisoFoam and simpleFoam and all
the corresponding tutorials have been updated and moved to
tutorials/modules/incompressibleFluid.

Class
    Foam::solvers::incompressibleFluid

Description
    Solver module for steady or transient turbulent flow of incompressible
    isothermal fluids with optional mesh motion and change.

    Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and
    pseudo-transient and steady simulations.

    Optional fvModels and fvConstraints are provided to enhance the simulation
    in many ways including adding various sources, constraining or limiting
    the solution.
