Title: qrenc: add output mode for drawing smaller QR codes using UTF8 box drawing characters

This patch adds "-t utf8" and "-t ansiutf8" to the qrencode tool, which outputs a QR code using UTF8 box drawing characters. This doubles the density of QR codes printed on terminals, and should be supported by virtually all modern terminals, including xterm, gnome-terminal and the Linux console.
