Update ubuntu templates
Rename 'ubuntu' template to 'lucid' Add new maverick and natty templates, which do much less tweaking of the environment. These should only be used on a kernel which supports sysfs tagging for /sys/class/net, as udev will be running in the container. The natty template needed to slightly change the installed packages for dhclient to be correclty installed.
