docs: Inserts an <img>
  If selection is already an image link, it removes it
  
  @example
  // either ...
  wysihtml5.commands.insertImage.exec(composer, "insertImage", "http://www.google.de/logo.jpg");
  // ... or ...
  wysihtml5.commands.insertImage.exec(composer, "insertImage", { src: "http://www.google.de/logo.jpg", title: "foo" });
