Title: Add API for rendering QR codes

This adds an API for rendering QR codes on IRC. This is useful, for example, for TOTP key enrollment (scan the QR code with your phone).

Caveats:

* Any IRC client which does not support rendering ASCII art will fail with this
* If libqrencode is not found, `command_success_qrcode()` does not presently send anything.
