Implement node-module add-on for native Windows file watching

Fixes brackets [issue #6551](https://github.com/adobe/brackets/issues/6551)- "[File Watchers] Can not externally rename a directory with subfolders on Windows"

Requires associated [pull request #6686](https://github.com/adobe/brackets/pull/6686) from brackets repo.

Calling a native node-module add-on in Windows requires that the node process be named "node.exe", rather than our renamed "Brackets-node.exe".  This change reverts our previous renaming so that we ship with "node.exe" instead.

NOTE: this pull request against the `release` branch replaces the earlier PR #412 against `master`.
