Search: pagination links should be rendered by xquery/template
the pagination in search.html is rendered by javascript (bootstrap pagination) after page load.
this has some problems:
* flickering when pagination javascript is applied
* dependent on bootstrap version, not template independent
* bootstrap pagination depends on jquery
* possible accessibility issues, is a screen reader able to mention javascript-generated links?
would be good to implement the pagination without javascript to be rendered server-side
