* Add checkbox to System -> Advanced -> Admin for HTTP_REFERER checks * Add and enforce HTTP_REFERER check if checkbox is not checked. This will prevent HTML pages from crafting HTML GETs against the web interface and will prevent firewall admins from being "tricked" into clicking on links that may be harmful to their firewall.
