Add prism.js support

With new syntax highlighter prism.js, you have to configure which syntax highlighter you want to use between _highlight.js_ and _prism.js_. **However if you don't configure it, no syntax highligh will be apply** (where previously _highlight.js_ was forced by default).

Please upgrade you're `config.toml` (you can checkout `exampleSite/config.toml` to see sample) to re-add _highlight.js_ as syntax highlighter (except if you don't need it):

```toml
[params]
  syntaxHighlighter = "highligth.js"
```
