patch: access clients to zabbix.

[zerg]

I'm longer deployment,support Cacti and Nagios. Zabbix are all about testing.
When I'm migrate from to system(nagios&cacti) in one(zabbix). One of the problem to grant access for my clients.
I'am work at middle ISP provider... Clients need access only for graph's or screens.

As i can see permissions at zabbix much more complex vs cacti.
But in cacti i can take permissions: oneuser<->onegraph.
In zabbix i can't take this scheme cause permissions setneuser<->onehostgroup.
For get like cacti permissions only for one/two graph, i'am
1)duplicate same Host(e.g. switch -> client-sw)
2)whith one/two ports(e.g. delete all not clients Ports Fa0/2-Fa0/48).
3)Add host to hostgroup (CLIENTNAME-CLIENTS).
4)Create Screens (CLIENTNAME-CLIENTS)
Finaly:
1)Create group(CLIENTNAME-CLIENTS).
2)Add permissions only for read(for group CLIENTNAME-CLIENTS)
3)Create user whith "user type" - "Zabbix Clients"

As you can see i'am generate new user_type - "Zabbix Clients".
If user list in this type - user can access only for charts.php and screens.php page...
