Add QR code in the lower right corner

This QR code points to the location of my CV.

The eso-pic package can only align let, so we need to add a box to force
the QR code to be in the right.

Putting it in the lower left corner would also be an option, but this
was a little harder due to the two-column layout, and I don't really
care either way.
