Restructured response submission

On response page, there are now 3 buttons (support,opposition,objections)
for showing responses by type, and a single 'respond' button that shows
the new response form.

The response type buttons can be toggled to show responses filtered by
type, or to show all response types together.

The new response form has a radio button group to specify the type of the
response.
