LP1850938 Angular Catalog Preferences Page

Adds a new "Catalog Preferences" interface, accessible directly from the
catalog.  The UI houses the search preferences (default search lib,
preferred library, default search tab), a new staff-specific
hits-per-page setting.  Other preferences may be added later.

Adds support for selecting a default search tab using the existing
'eg.search.adv_pane' setting.

Reduce API call count by loading more of the catalog preference settings
in the main batch invoked by the page resolver.
