Added the option to pass the Zabbix server host/ip and port. This is in case the Zabbix server is in a different location than the monitoring script. Also fixed an issue when getting an empty value pair for the extra_info_page_faults. When it is emtpy a valid key value pair is not created and zabbix_sender fails.
