OFBIZ-6277: new Configuration() is deprecated; instead, the desired freemarker version should be passed in. To make it easier to control the version centrally, add a helper method on FreeMarkerWorker that wraps the instantiation of the Configuration object. git-svn-id: https://svn.apache.org/repos/asf/ofbiz/branches/OFBIZ-6275@1675521 13f79535-47bb-0310-9956-ffa450edef68
