- Added: remoting queries with a lot of results (e.g. email addresses or alias domains or dns rr) lead to non-functioning soap requests
  - added '#OFFSET#' AND '#LIMIT#' handling to the query
  - added automatic 'WHERE 1' if an empty array was given as query
  example: $result = $api->sites_web_domain_get('type' => 'vhost', '#OFFSET#' => 25, '#LIMIT#' => 50); to get the websites 26 to 75

- APS Installer: if website has no compatible PHP mode enabled (FastCGI with SuExec or PHP-FPM), change it.
