Reset third_party with build

[jeffposnick]

I'm still not seeing the correctly rendered, syntax-highlighted code blocks.

Here's what I see when checking out your branch, running npm install, gulp clean, gulp serve:prod, and then visiting http://localhost:3474/get-started/webpack.html:

Is there a specific gulp task that converts the Markdown into prope code blocks? If so, perhaps it's not listed as a dependency of gulp serve:prod and I need to run it explicitly?

FWIW, the Markdown to <pre> + <code> conversion seems to be failing for me, rather than something specific to Prism. (I see the prism.js and prism.css both loaded now).

I get the text whose source is in the ``javascript code blocks wrapped in

tags instead of

+`:
