Add QR code for tempalinks (#97)

* Add QR code of tempalink

* add padding to the bottom of the QR code

to ensure that there's space to scroll down far enough so the footer 
isn't covering the QR code

* Fix spinner css

Use a rotating css background image instead of a separate element placed 
behind

This allows flexbox to function correctly
