Minifyied version for browser

Add minifyied version for using in browser.

This package is really really large for the browser. Also with minification; it still requires unicode/so.js which alone is 1.68 MB minified.

I've switched to slugify, as this package doesn't seem to be maintained and its way to big. (Latest commit 85ded30 on 18 Apr 2015)
