Use e.g. Waypoints to partially render the search result lists

Description of the enhancement

There is probably no point in rendering all the search results when we have a lot more of them that can fit in a browser screen. Implementing a partial load would be a good idea - previously in Skosmos 2.x this was done with Waypoints.

Who are the users that would benefit from the enhancement and how?

Each rendering of a search result hit triggers calls for resolvling uri resources, translation strings, etc. At some point rendering all of the results at once will result in long page loading times. As the search strings contain an implicit wildcard character in the end, it is possible to get hundreds of hits for a short search term. These would be improved by partial rendering of the list.
