- easier to test or use different versions

- change WM_CXXFLAGS to -std=c++11 instead of -std=c++0x

- adjust so that the final -option is taken. This is consistent with
  other Unix tools.

ENH: short-circuit to avoid directory check on non-master node

- tends to obscure what is going on and isn't needed either.

STYLE: adjust documentation. Accept std::string as parameter in more places.

- the purpose is more explicit, without needing to check documentation
  about what the bool parameter means.

STYLE: improve formatting of fileName documentation

- was previously only within string expansions, but cover dictionaries
  as well for consistency

ENH: replace the never-used fileName::caseName() functionality

- stringOps::inplaceReplaceVar() is more general

     stringOps::inplaceReplaceVar(myfile, "FOAM_CASE");

STYLE: relax parameter passing when calling some POSIX 'query' functions.

- A std::string is sufficient since the functions use a plain C-string.
  Eg, getEnv("SOMETHING").
  Retain more stringent Foam::word for things like setEnv, since this
  could be useful.

- the regex was not being unset on assignment.
- drop unused recompile() method as being dubious

- caused by the typo '@E' instead of '$E' (commit 997f1713)

ENH: minor improvements for wmake/src makefile

- 'make clean' now also tries to remove the parent platforms/
  directory if possible.

- the flex intermediate build target is placed into the platforms/
  directory to avoid touching the src/ directory at all.

- suppress warnings about unused functions (GCC only)

- makes it possible to filter out or highlight messages originating
  from wmkdep in the build process.

And correcting bool entry from dictionary in fanFvPatchField BC

- now explicitly check for "SOLID" or "solid" in the header

- does not affect triSurface in the master branch, since that used a
  different parser.

- for symmetry with MeshedSurface etc.

Subset list

See merge request !97

- determines a unique sort order (as per uniqueOrder) and uses that to
  reorder the list and possibly truncate it.

- these are suitable for use with lambda functions.

- Deprecate the unused 3-parameter version of subset/inplaceSubset.

- Deprecate initList and initListList in favour of initializer_list

STYLE: adjust some comments, remove dead code in regionSizeDistribution.C

- do not enable function objects by default if there is no means of
  disabling them.

This helps on bounding Twall on cases where large inertia is found in the first cell
next to the fluid (i.e large cell, rho or Cp)

Fixes #416

Closes #416

This scalar allows to introduce a factor for cloudy sky between 0 (clear) and 1 (fully cloudy)

Improvements, adjustments for build scripts and infrastructure

See merge request !94

- new behaviour is to do nothing if no platform was specified.
  This helps avoid inadvertently removing files.

- support special platforms for compatibility with wmake/wclean targets.
  Eg, "wcleanPlatform all"

- allow use from ThirdParty top-level as well, since the directory
  structure is similar.

BUG: fix regression in wcleanLnIncludeAll introduced by 9e2e1115

Can now use this:
    _foamSourceEtc config.sh/scotch
    _foamSourceEtc config.csh/scotch

instead of this:
    _foamSource $($WM_PROJECT_DIR/bin/foamEtcFile config.sh/scotch)
    _foamSource `$WM_PROJECT_DIR/bin/foamEtcFile config.csh/scotch`

In the bash/sh version, leave the _foamSource function for now, since
ThirdParty is still relying on it.

STYLE: elminate while-loop for _foamAddPath etc since this type of
construct isn't readily possible for csh and isn't being used anywhere.

- Eg, instead

      if file=$(foamEtcFile filename)
      then
          . $file
      fi

  can write

      eval "$(foamEtcFile -sh filename)"

  Also supports -verbose reporting, which is especially useful for csh,
  since it allows simplification of aliases and allows the message to
  land on stderr instead of stdout.

      eval `foamEtcFile -csh -verbose filename`

Use subDict for changeDictionary, Fixes #409
