Subject: [PATCH] Bug 42107: Add search scores to staff results page

This patch ensures the scores from ES are passed through and added to the
search results in the staff side.

Initially hidden, the scores can be shown by entering the line below into the
JS console in developer tools in the browser, or added to IntranetUserJS to
make them always show:
$(".search_score").toggle();

To test:
1 - Have Koha using ES
2 - Do some searches, note results
3 - Apply patch, restart all
4 - Confirm results don't change
5 - Enter code from description into IntranetUserJS
6 - Do more searches
7 - Note the score is visible

To really note scores, you will need to add some weights to the ES config:
Set weights like:
title 32
author 16
subject 8
