QR codes update

Just followed the link on @tombarrett's tweet on QR codes http://bit.ly/bYDi10 and learned something new :-)
If you use a URL shortener like http://goo.gl and create a short URL, add .qr at the end of the short URL and you will get a QR code!

For bit.ly, you add .qrcode

Guess there's no need to use http://splashurl.net anymore!
