Pinba Script Name Fix

By default Pinba PHP Extension sends value $_SERVER["SCRIPT_NAME"] in script_name. Sometimes it is not informative, for example when web application has one entry point. This plugin sends $_SERVER['REQUEST_URI'] instead. This plugin is for use on a wordpress blog, on a server with PHP Pinba Module Installed. References:
