0.0.31

• Renamed test git-versioning to git-versioning-spec to follow name
  convention.

• Documentation restructured. Fixes, updates.
  Added reference to project GitVersion.

• Removed V_PATH_LIST. Started read_nix_style_file.

• Added modus without versioned-files.list (and main document with version).
  VER_STR must be provided in the environment, the files to be checked are
  read from standard-input.

  For example to go without .app-id and .versioned-files.list or main
  document::

  cat my-file.list | APP_ID=myproject VER_STR=1.2.3-alpha git-versioning check

  For this the parameters of the V_CHECK script (tools/cmd/version-check.sh)
  have been changed and are incompatible with previous.

• Proper production release failed, see next version.
