Tell the selected submit button to the server.

Browse Source 
Commit 9cc9db4e24e54499e3736d14563ee2721012d724 broke submit buttons
on HTML forms, so that the server no longer knows which button was
actually pressed.

<kahmalo> The bug with forms seems to be that try_submit_given_form (in
          src/viewer/text/link.c) is the only function that runs "onsubmit"
          scripts, and it does not care which of the submit buttons was
          pressed; it calls submit_given_form which submits based on the first
          item of the form.                                             [20:57]
<kahmalo> or last, I don't know how the list works.
<kahmalo> try_submit_given_form could get the control via
          get_current_link(doc_view) but I suppose it'd be cleaner to provide
          that as a parameter.                                          [20:58]
