Template: utils.html

[hbueno]

Create a dedicatede template file utils.html. A place to define well-named reusable variables.

Quoting from Urubu's manual:

Suppose these variables are defined in the file '_layouts/util.html'. We can import them in any content page as follows:

{% from 'util.html' import open, done %}

Note that Urubu knows to look up util.html in the '_layouts/ directory,' because that is where templates should be located.

According the Basic Use struction from Font Awesome, using a <span> tag instead of <i> tag is more semantically correct. See also CSS Pseudo-elements.
