Fix question submission button (now does nothing on return key)

According to some w3c spec, a form with exactly one text input
field will be "submitted" upon press of the return key by submitting
"synthetic click events" upon the first submit button within the
form. Well, surprise surprise... browsers don't do this. Even though
the question form has no action, chrome just appends the urlencoded
form to the current url, which breaks the form if people press
return. This doesn't apply to any of the other improvement forms
because they have more than one non-textarea input field. Ay ay ay.
