Availability Reports by trigger template

[giovibal]

This patch enable "filter by group" parameter in availability reports/by trigger template filter form; it applies to zabbix version 1.8.4.
In file report2.php, at line 214 add this lines:

if(isset($_REQUEST['hostgroupid']) && ($_REQUEST['hostgroupid'] > 0)){
$sql_from.=',hosts_groups hg ';
$sql_where.=' AND hg.hostid=h.hostid AND hg.groupid='.$_REQUEST['hostgroupid'];
}
I hope developers extends e debug reports in zabbix.
