Does not work without HEAD tag.

Understanding that including the tag is best practice, it would nevertheless be good to throw an error/warning if the template does not have a tag into which to inject the livereload.js script. I spent some time with some very basic HTML file trying to get this to work, only to realize that it was not loading because I did not have a element.

same here, it would be nice to mention it somewhere in the readme.
