BUG: Removed call to topoChanging(false) in interDyMFoam and compressibleInterDyMFoam - see #363 and 03db8627

Example use

    foamGrepExeTargets           > targets-available
    foamGrepExeTargets -appbin   > targets-created

    diff -uw targets-available targets-created

- this is apparently not uniform across systems

STYLE: unify the date format in logfile

This reset the flag from any previous topo changes

- Could be related to interrupted builds.
  So if there are any parts of the build that rely on an explicit
  'wmakeLnInclude', make sure that the contents are properly updated.

--

ENH: improved feedback from top-level Allwmake

- Report which section (libraries, applications) is being built.

- Provide final summary of date, version, etc, which can be helpful
  for later diagnosis or record keeping.

- The -log=XXX option for Allwmake now accepts a directory name
  and automatically appends an appropriate log name.
  Eg,
      ./Allwmake -log=logs/  ->> logs/log.linux64GccDPInt32Opt

  The default name is built from the value of WM_OPTIONS.

--

BUG: shell not exiting properly in combination with -log option

- the use of 'tee' causes the shell to hang around.
  Added an explicit exit to catch this.

--

- Detecting the '-k' (-non-stop) option at the top-level Allwmake, which
  may improve robustness.

- Explicit continue-on-error for foamyMesh (as optional component)

- unify format of script messages for better readability

COMP: reduce warnings when building Pstream (old-style casts in openmpi)

- wm32/wm64 were for changing between -m32, -m64 builds on x86_64
  architectures. This is seldom enough not to warrant a special alias.
  Also ambiguous if these could refer to label sizes.

- Remove wm32,wm64 aliases.
- Add wmInt32, wmInt64 aliases for switching WM_LABEL_SIZE.

- can compile with icc 17.0.1
- note the min gcc versions needed to compile clang

ENH: ensure averaging flags are not 'sticky' (see issue #331)

ENH: InjectedParticleDistributionInjection  model - added protection for the case of zero particles; updated tutorial scripts.  See #363

BUG: Tutorial updates - updated rhoSimpleFoam thermo to use rhoThermo after commit a7c8d1cf - see #355

scalarTransport does not generate its own phiMean anymore but it is given from the user.
This "flux" can be generated using the "flux" FO

- fixed library path for VTK.
  They should use lib/ and not lib64/

- cleanup some code in foamInstallationTest
