[PATCH] Add ENV variable to force qrcode rendering in terminal

[Marcus Hildum]

I prefer to have my qrcodes rendered in the terminal and currently
pass defaults to using feh, graphicsmagick, or imagemagick (in that order)
to render qrcodes if they're installed. Given that many other parts of pass
are customized with environment variables I figured that was a good way to
force terminal rendering if the user so chose.
