-Added a new `shared_pages.page_header.search.position` setting that determines where the search bar is located (valid options include the old 'below-header' and the new 'inside-header' options)
-`shared_pages.page_header.show_search` setting has been re-mapped to `shared_pages.page_header.search.enabled`
-Updated the search placeholder locale text
-Changed the Explorer menu item icon from a magnifying glass to a cubes/blocks icon
-Updated css rules to fix some small glitches and allow the new 'inside-header' search option to function
