Changed to after(errorEl) for the sake of screenreaders
Screenreaders don't automatically see DOM elements inserted before inputs
Inserting errors after the relevant input allows blind people to easily recieve these errors if the site uses happy.js
Where I learned this was: http://alistapart.com/article/designing-for-easy-interaction
added role=alert for accessibility too
