Grouping views and collections with the same access lists saves space, but
is confusing for users because secret urls must remain per-view and per-
collection and cannot be grouped together.

This change displays a single row for each view & each collection, and just
repeats the access list for view/collection with the same access list.

This allows the get_accesslists function to be simplified; most of its work
can now be done by the existing get_views_and_collections function instead.
