v1.6

public release v1.6

    * NEW: Executable version. Implemented `-unpack` command.
           To generate minified version from executable.
           ```
           gnt -unpack
           ```

    * NEW: Executable version. Implemented `-msbuild` command.
           To use specific msbuild for executable version.
           ```
           gnt -msbuild "D:\MSBuild\bin\amd64\msbuild" /p:ngpackages="Conari"
           ```

    * NEW: Added ';' splitter for .config files.
           The `|` now is marked as obsolete and can be removed in new versions.

    * NEW: MSBuild-helper with `-notamd64` option.

    * FIXED: Part of unhandled exceptions has been changed on messages to stderr:
            `The "PrepareList" task failed unexpectedly / FileNotFoundException`
             The "NGPack" task - DirectoryNotFoundException & The "NGDownload" task - WebException 404

    * CHANGED: Value of `ngconfig` property now is `packages.config` by default.
