Add the ability to define a default language (#206)

Browse source 
* Add the ability to define a default language

I don't want to have to add the language i'm working on to every single block nor do I want to rely on a default heuristic to find the language.

This adds the ability to write

```
highlight: { defaultLang: 'xxxx' }
```

in `siteConfig.js` to force the language when not specified.

I tested it without a a highlight block, without a defaultLang attribute and with one and with a wrong one. All of them work as expected.
