Allow users to toggle individual group filters

[fkusei]

I have these group_filters:

{
    "group_filters": {
        "host_groups": ["itinfra_all", "haus-event-monitoring", "itinfra_services_for_betriebspakete"],
        "service_groups": ["itinfra_all", "haus-event-monitoring", "itinfra_services_for_betriebspakete"]
    }
}

Sometimes, i'd like to remove one of these groups to have a better overview about stuff i still need to handle, so it would be nice if users could toggle individual filters instead of just all of them.
