Title: Bug 949170: Fix FTU basket XHR.

I believe this is the fix we need. The crux of it is
the additio of the Content-type header and the urlencoding
of the email address. I tried to get this to work in a testing
packaged app on my geeksphone, but I was having API and permissions
issues I believe. Please give this a try and let me know if this helps.
