Cleaned up use of tcprelay (now handling logins locally).
Replaced logoutip/logoutmac with logoutnet (which gathers ip/mac from firewall instead of arp... may be expired)
bytesused now pings with current IP address
checklogins now times out any user that is not "active" (not just "bad" users)
status.php logs out using logoutnet now.
Merge branch 'master' of https://github.com/downwa/iglooportal
