Subject: [PATCH] Ability to tweak the prism language (#146)

I want to be able to tweak the default tokenizer for syntax highlighting. The current one isn't as good as it could be.

With this PR, I would be able to add this to the siteConfig and it would give me the Prism access so that I can get proper syntax highlighting:

```js
  prism: function(Prism) {
    Prism.languages.javascript = Prism.languages.extend("javascript", {
      keyword: /\b(alias|as|async|await|base class|...|with)\b/,
      constant: /\b[A-Z][a-zA-Z0-9_]*\b/,
      builtin: /\bopen_file|...|invariant_violation|invariant|getcwd\b/,
      function: /\b[_$a-z\xA0-\uFFFF][_$a-zA-Z0-9\xA0-\uFFFF]*(?=\()/,
    });
  },
```
