#136: Unicode-Windows-API for file operations

- internally all paths are handled in UTF8;
- all paths are stored in config-file in UTF8;
- when calling file access Windows API functions the paths are
converted to wide-chars and Unicode-API is used;
- extra long paths are prefixed with “\\?\” (extended path format).
