The search results page showed just the titles of the found matching
pages / sections but not their location within the admin tree. In
certain cases, we even have multiple admin pages with the same title -
making it impossible to distinguish which is which.
The patch makes it so that the path of the found admin page / section is
displayed below the title.
Admin search page was processing the blocks delete request before the blocks
could process it.
Added a hidden field to the search results form so it can be sure the form submission
was for saving admin settings.
