Add fences as simple alternative module

Problem/Motivation

Hi, I just came across this great module and think it would make sense to connect it with the very widely used Fences module. Both solve different levels of complexity.

For that reason I added the following to the Fences module page:

<h3>Alternatives modules</h3>
<ul>
  <li><a href="https://www.drupal.org/project/custom_formatters">Custom Formatters</a> is a helpful alternative or addition if what Fences does is not enough and you need custom formatters without writing module code.</li>
</ul>

I think it might make sense to add something vice-versa to the custom_formatters module page, e.g. suggesting fences for adding classes to existing formatters, removing wrappers or changing formatter elements - for cases where a custom formatter would just be too heavy.

What do you think?
