New package: qrencode 3.0.3

Libqrencode is a C library for encoding data in a QR Code symbol, a kind of
2D symbology that can be scanned by handy terminals such as a mobile phone
with CCD. The capacity of QR Code is up to 7000 digits or 4000 characters,
and is highly robust.

This package installs a library and a command line tool.

Package from Alaric Snell-Pym, with some improvements by me.
