Show QR codes when not logged in

[grctest]

Is your feature request related to a problem? Please describe.
If I want to create a QR code to transfer funds from one account to another using the QR code, then I need to be logged into the bitshares wallet, at which point the QR code is negated unless you're logged in with a limited account of some sort, as you can just click send/submit instead of needing to use a key manager with the qr code.

Describe the solution you'd like
Rather than disable submitting forms when not logged in, offer an optional QR code to be scanned by an external key manager.

Describe alternatives you've considered
Logging in and saving the QR codes for later use.
Generating the QR codes without bitshares-ui

Additional context
For use with Bitshares beet wallet.
