Code review comment for lp:~osomon/webbrowser-app/http-auth

I tested with http://studiare.unife.it and works very well \o/
I hope it lands with OTA-5, I need to be able to take a look to my uni website when I'm on the phone, so thank you very much :-)

The only thing that could be improved it's the support for the 'tab' key to switch between fields. Anyway, this isn't prioritary, so it's a green light for me!

(as usual, I didn't review tests, they looks good but you know I don't know python)
