changeDictionary: Simplified by removing the need for the superfluous dictionaryReplacement sub-dictionary

Added the option '-subDict' to specify a sub-dictionary if multiple
replacement sets are present in the same file.  This also provides
backward compatibility by setting '-subDict dictionaryReplacement'

multiphaseCompressibleTurbulenceModels, twoPhaseCompressibleTurbulenceModels, phaseCompressibleTurbulenceModels: Added LIB_LIBS

    postProcess -func 'totalPressureIncompressible(U,p)'
or
    postProcess -func 'totalPressureCompressible(rho,U,p)'

To re-use existing 'sampleDict' files simply add the following entries:

    type sets;
    libs ("libsampling.so");

and run

    postProcess -func sampleDict

It is probably better to also rename 'sampleDict' -> 'sample' and then run

    postProcess -func sampleDict

e.g.
postProcess -func probes

or

postProcess -func 'probes(p, U)'

Replaced the 'postProcess' argument to the 'write' and 'execute'
functions with the single static member 'postProcess' in the
functionObject base-class.

e.g.
    postProcess -func 'patchAverage(name=inlet,p)'
    postProcess -func 'patchIntegrate(name=inlet,p)'

In parallel the sets are reconstructed. e.g.

mpirun -np 6 checkMesh -parallel -allGeometry -allTopology -writeSets vtk

will create a postProcessing/ folder with the vtk files of the
(reconstructed) faceSets and cellSets.

Also improved analysis of disconnected regions now also checks for point
connectivity with is useful for detecting if AMI regions have duplicate
points.

Patch contributed by Mattijs Janssens

Resolves bug-report http://bugs.openfoam.org/view.php?id=2116

Replaces expandDictionary utility

stressComponents: utility replaced by the 'R' and 'components' functionObject used with the '-postProcess' option

createTurbulenceFields: utility replaced by 'turbulenceFields' functionObject used with the '-postProcess' option

Replaces the dictionary access functionality of foamInfoExec and
provides additional options to edit individual entries.
