User Agent v1.6 changes:
1) Added links to username and ip address
2) Added code so that forum_list and thread_view now update the list User Agent data.
3) Added target="_blank" for ip link.
To update from v1.5, copy folder library/Andy/UserAgent to your server and do a XML upgrade.
To update from earlier versions, do a complete uninstall of the add-on and a new install.
