Subject: make icon its own module (#95)

abstract the method to make icon markup into its own module.

this allows for it to be used in JavaScript environment that does not
have access to nodeism like `fs` or `__dirname` (such as browserify or
webpack).

this method could potentially be re-used in the browser asset
bundle, as it is the same.
