Added newline
Adds field translation to SearchForm

The search is performed with several GET values for "tag=a&tag=b", but
the search form wants a single field called "terms".

Eventually, the "terms" field should really be modified to use a widget
to explicitly pack multiple values, cleaning to actual Tag objects.
Updated list view to match home view's improvements

the search form's ability to populate it's data, and should probably be
removed.
Perform an AND search on tags, not OR
