Modify Class button forces 127.0.0.1 in URL

[Andy Powell]

The "Modify Class" button uses 127.0.0.1 in the URL irregardless of the URL used to access the page.  This is a problem when managing remote servers -- the operator is required to change the IP on the browser's location bar after clicking on the button.  Using version 1.3.9 on RedHat EL4.
