* Search URL is https://www.wikidata.org/w/index.php?{query}&ns0=1 (with ns0=1 at the end to avoid an HTTP redirection)
* url_detail: remove the disabletidy=1 deprecated parameter
* Add eval_xpath function: compile once for all xpath.
* Add get_id_cache: retrieve all HTML with an id, avoid the slow to procress dynamic xpath '//div[@id="{propertyid}"]'.replace('{propertyid}')
* Create an etree.HTMLParser() instead of using the global one (see #1575)
