Template Changes

Value type was changed from "Numeric (unsigned)" to "Numeric (float)" for items system.stat[kthr,b] and system.stat[kthr,r] in Template OS AIX. Both items were also added to "Performance" application.

In order to fix it, import this template from https://www.zabbix.org/wiki/Zabbix_Templates/Official_Templates.
