which may be optionally overridden by version-specific rules.

For example the default rules for gcc on GNU/Linux x86_64 are in the
wmake/rules/linux64Gcc directory.  If there is a need to change any of
the rules for a specific version of gcc, e.g. gcc-4.8.4 the directory
wmake/rules/linux64Gcc48 may be created into which any of the language
files may be provided containing the rules to override the defaults.

The Makefiles are now in the makefiles sub-directory

The "-f | -force" option in wmakeLnInclude is now "-u | -update" for
consistency with the other scripts.

The "Usage" entry in the headers is now consistently formatted in all
scripts.

- reduces verbosity for dynamicCode

- non-silent wmakeLnInclude output to stderr to avoid polluting logs

- replaces previously used 'bin/'

STYLE: add -help to makeWmake

- platforms/WM_OPTIONS/lib
      old: lib/WM_OPTIONS

- platforms/WM_OPTIONS/bin
      old: bin/WM_OPTIONS
      old: applications/bin/WM_OPTIONS

A runtime environment nows needs
    - bin/
    - etc/
    - platforms/

- more consistent script names
- remove '-help' option from internal scripts

- simplified the logic
- provide direct link to the respective scripts
- provide help from the respective scripts

- update foamPack* scripts accordingly

- change name of environment variable from $WM_OS -> $WM_OSTYPE
  as a better description

- place wmkdep and dirToString executables under
  utilbin/$(WM_ARCH)$(WM_COMPILER).
  This helps somewhat when copying rules about, and might help when creating
  general rules.

Removed THIRD_PARTY.If such a variable is needed it should be WM_THIRD_PARTY and set in thesettings.?sh.
