.files: lists of win32 binaries from `node.js`, `node-webkit` and `cygwin`

* MS Windows setup requires this files in respective directories
* `cygwin` set is minimal for `_devel_backend.sh` to work; also it is
  quite old ~ 11.11.2011

The `node-webkit` is used under win32 mainly to launch `node.js` in
background and without black console window; also to have possibility
to make POS or Kiosk setups without any other (i.e. explorer) app running.

Under GNU+Linux `node.js` must be installed in any "{/usr{/local}}/bin/".
This is setup for web demos of apps using this platform.
