Add page breadcrumbs to search results

[zenoachtig]

• Add the newly-available page ancestor information to search results in the form of page breadcrumbs.
• If there are too many breadcrumbs, we only show the 1st, 2nd, and last crumb.
• Also filtered out translation variants from taking up a breadcrumb.
• Cleaned up the display of breadcrumbs a bit.
