[bug 1110543] Add noscript section

Adding the <noscript> section to both the generic_feedback.html and picker.html templates allows the message to stay displayed when the user picks a product without JavaScript being enabled.
Having said all that, I really think if someone has disabled JavaScript, then they know how to re-enable it. Plus SUMO doesn't work well if the user has JavaScript disabled. I think for now I'm inclined to just leave out that instructive sentence.
