Add support for liquid templating language? (Jekyll and Shopify)

[adrianocr]

I was wondering if it's possible to add support for the liquid (https://github.com/Shopify/liquid) templating language? It's used by Shopify and Jekyll among a few other CMS's and services.

It's pretty much raw HTML with a special syntax for outputting things like Twig.
Example: {{ variable }} would output whatever value is assigned to variable.

You don't really use class names in the helper syntax except for like two cases. So really it just needs to parse the HTML.
