[REVIEW-ONLY] Implement node-module add-on for native Windows file watching

Fixes issue #6551- "[File Watchers] Can not externally rename a directory with subfolders on Windows"

Requires associated [pull request #]() 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.
