[Jenkins-events] QR code on name tags

There was an off-list conversation about how to connect sponsors to 

The last year several people felt really mad about one of the sponsors 
calling them up unsolicited, so this year we've added the opt-out 
option. Then we've heard from sponsors that it got in the way of 
connecting with people who they had good conversations in the booth.

So the topic of QR code came up once again. Alyssa said this off-list:

I haven't looked around carefully, but I'm pretty sure I can find a 
library that generates a PNG image of the QR code for arbitrary payload.

So the only remaining question to me is, how to integrate that with the 
current way Alyssa prepares name cards --- we need to insert the QR code 
image en-mass.

I suspect generating HTML would be the easiest. The layout will probably 
be imprecise, but I don't think it'll be an issue.

Alternatively, maybe we can hack up a quick PDF generation with a 
library like [1] and that'd give all the control we need with more room 
for extension?
