Added steno.js

[steno.js](https://github.com/kenshinthebattosai/steno.js) is a javascript library to write shorthand HTML, using CSS selectors you already know and use.

Added min, sourcemap, original files and a crushed version by `http://www.iteral.com/jscrush/`
minified files are enough for production, its best to remove `steno.js`
