Overview

scrub!(:targetblank)

+:targetblank+ adds a target="_blank" attribute to all links.
If there is a target already set, replaces it with target="_blank".

   link_farmers_markup = "ohai! <a href='http://www.myswarmysite.com/'>I like your blog post</a>"
   Loofah.html5_fragment(link_farmers_markup).scrub!(:targetblank)
   => "ohai! <a href='http://www.myswarmysite.com/' target="_blank">I like your blog post</a>"

On modern browsers, setting target="_blank" on anchor elements implicitly provides the same
behavior as setting rel="noopener".
