Merge 98d9d7d170 into c30ee7d885

This adds syntax detection for HAML files.

An example would be if using classes provided by [Tailwind CSS][1]

IE:

```html
<div class="flex sm:inline-flex md:block lg:hidden xl:flex ...">
  <!-- ... -->
</div>
```

```haml
.flex.sm:inline-flex.md:block.lg:hidden.xl:flex
  # ...
```
