Redirect to the map, streamline authorization in url

The main idea is to look after "zabbix.php" and replace every "&" with "%26".

Before:
http://192.168.88.55/zabbix/index.php?name=Admin&password=zabbix&enter=Sign%20in&request=zabbix.php?action=dashboard.view&ddreset=1
After:
http://192.168.88.55/zabbix/index.php?name=Admin&password=zabbix&enter=Sign%20in&request=zabbix.php?action=dashboard.view%26ddreset=1
