Vmbuilder

* Fix bug 1659952. Fail with conflict resolving during packages upgrade
* Fix bug 1544042. Fail with unmounted /proc directory during install kernel

* Revive firstscripts plugins. This fixes the --firstboot and --firstlogin
options, both of which went missing with 0.12.
* Make Plugin.install_file work in non-context plugins (plugins that are not
Distros or Hypervisors).
* Do a slightly better job at cleaning up after ourselves by removing the
distro chroot by default and removing the temporary root mount point.
* Revive QEMu hypervisor.

* Reworked the way timezones and locales are handled. This fixes an
actual problem with /etc/localtime not being set correctly, and fixes
a theoretical problem with people not running VMBuilder on Ubuntu.
* Resurrect -o (--overwrite) which went missing with 0.12.0.
* Resurrect Xen support which went missing with 0.12.0.

* Moved test directory under VMBuilder/ and include it in the tarball.
* Revive ubuntu-vm-builder (which rotted during the 0.11 -> 0.12 transition)
* Skip tests that need root, if not run as root.
* Fix installing onto logical volumes.
* Fix --raw handling.
* Refresh documenation in disk.py
* Improve handling of non-string settings from command line and config files.

* Update postinst plugin to 0.12 API.
