Turns selection into a link
If selection is already a link, it removes the link and wraps it with a <code> element
The <code> element is needed to avoid auto linking

@example
// either ...
wysihtml5.commands.createLink.exec(composer, "createLink", "http://www.google.de");
// ... or ...
wysihtml5.commands.createLink.exec(composer, "createLink", { href: "http://www.google.de", target: "_blank" });
