Whitelisting jekyll-webpack

[VorontsovIE]

I'm working with gh-pages v228. I want to publish a Jekyll site with some React code bundled with a webpack. Locally I'm using jekyll/webpack plugin.

Locally it works (e.g. my blog has webpack dependencies - see repo) and bundles my webpage even in live reloading mode.
But it doesn't work on a hosted version, thus I need to manually bundle my source code and put bundled files under a git supervision.
Nothing critical, but I think it'd be more convenient to bundle code on a github server.
