[Delivers #47583949 #43515659] View all record links

Have reformatted the related resource, accession links as tables.

Also now embed the record search for subjects, locations, classifications and agents on their read only template.  This is an ajax call that is fired once the page has been loaded.

Fixed a few i18n omissions.

Replaced the entity &#160; with some CSS.

Fixed locations not sticking on the Archival Object container form.

Refactored the agent routes to use "agent_type" rather than "type" as "type" was conflicting with the search params use of "type".
