Rename global search to "Album Search" and group results by album

Photo search was returning every individual matching photo, which
was overkill for what's meant to be a quick way to find an album.
/search now groups matches by album (cover thumbnail + match count)
instead of listing each photo, and is relabeled "Album Search"
throughout the UI.
