Replaced the "bundle" script with a cross platform Node script called "bundle.js" (modeled after the original).

Added "del-cli" as a dev dependency, as a cross platform replacement of "rm".

Changed the quotes in the "if-node-version" call to doubles, to prevent dummy file being created on Windows.
