Investigate using functions directly in .pug templates

[brewingcode]

pug-pack is heavily inspired by https://github.com/jescalan/roots, and one of the things roots does is use JavaScript functions as template variables:

html
  head
    != css()

In development, this would output a series of <link> tags for each css file. In production, it would output a single <style> tag with all the css files minified and concat'd together.

This is also shorter than the :inject(...) custom filter syntax.
