Zabbix

..F....... [ZBX-8671] Changed several API calls to return only boolean values to check permissions since no fields are requested in output. In item prototype edit form changed permission check from itemprototype.get to itemprototype.iswritable. In graphs moved group permission to be validated first and then other parameters, and added missing parameter for getting graph discovery rule. Separated display logic for trigger prototype list and fixes several coding style issues.
