Summary:

My changes:
- add curl collector for apache (ssh is not solution for me)
- separate reusable code from scripts ss_get_*, simpler work with new
collect scripts
- add collect script for xml statistics from statistics-channels bind
9.5, alredy without usable templates but collector works
- change cache management, simpler usage (dedicated function)

Most of the changes are copy/paste.  In the last release I re-implemented the
cache-file functionality and changed things a lot, so most of it doesn't apply
anymore and/or I've already duplicated the work :-(  However, getting stats by 
curl
is something I want to integrate.

Summary was: Integrate changes from Artur Kaszuba

The main bit of code here is this:

function get_url_by_curl($url, $auth=null) {

   $c = curl_init();
   if ($auth) {
      curl_setopt($c, CURLOPT_USERPWD, $auth);
      curl_setopt($c, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
   }
   curl_setopt($c, CURLOPT_CONNECTTIMEOUT, 30);
   curl_setopt($c, CURLOPT_URL, $url);
   curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
   $ret = curl_exec($c);
   curl_close($c);

   return $ret;
}
