Webpack Config updates

[denoteit]

• Running webpack,config,js throws error on Windows, updated to use path module (based on webpack's documentation - https://webpack.js.org/guides/get-started/#using-webpack-with-a-config).
• Added CLI task for Windows (based on webpack's documentation - https://webpack.js.org/guides/get-started/#creating-a-bundle).
