- Implemented json remote handler, example:

  http://yourispconfig:8080/remote/json.php?sites_web_domain_get
  with POST data:
  session=12345678901234567890123456789012&data=%7B%22type%22%3A%22vhost%22%2C%22active%22%3A%22y%22%2C%22php%22%3A%22fast-cgi%22%2C%22fastcgi_php_version%22%3A%22%22%2C%22%23LIMIT%23%22%3A1%7D
  where data is an urlencoded json-object of the params array used in SOAP api.
