Minify all JS and CSS via middleware. This means JS or CSS anywhere in the site is minified, not just in the Sprockets-controlled directories. I've also added inline CSS compression, and handling of several common "guards" that get wrapped around JS. Also, leave alone non-JS script tags (which may contain something like jQuery templates). Sprockets no longer has anything to do with minification after this.
