Displaying passwords as QR codes

[Corey Moncure]

Hello Password-Store,

This is my first post to the list so please forgive any breach of
etiquette.

What about adding an option to the show() command that would display
the password in the form of a QR code, for convenient transfer to
unsupported devices?

It could be achieved simply enough using the well known `qrencode` and
`display` from ImageMagick.  I have put together a provisional patch
that is working, but not thoroughly tested.  I am no master of bash
syntax so there are bound to be some issues. 

Anyway please have a look.
