[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.
The `noscript` shouldn't be of class error. You should have the `<p>` outside the `{% trans %}` tags and that should have class error.

Generally, we don't want to put HTML in the strings that localizers translate because it means we can't change it without changing the string requiring them to re-translate and they sometimes do funny things with HTML which causes problems.
