Ben Busby 137b0ef8db Added header template for autocomplete on results view
New header template adds full control over search field on desktop and
mobile, which now allows for autocomplete suggestions on the
results page

Also fixed autocomplete results format, since opensearch requires a
suggestions response of [<original query>, [<suggestion array>]]
