[ Michael Vogt ]
* integrate base-installer as a sub-component into the
  release upgrader and use the base-installer/kernel/*.sh
  functionality to ensure we select the most appropriate
  kernel on upgrade (LP: #353545)
* integrate automatic updates to base-installer into the
  pre-build.sh bzr hook
* UpdateManager/Core/UpdateList.py, UpdateManager/UpdateManager.py:
  - filter warnings
* UpdateManager/SimpleGtkbuilderApp.py:
  - use logging instead of sys.stderr
* data/glade/UpdateManager.ui:
  - set explicit translation domain
* integrate base-installer component into auto-upgrade-tester

[ Steve Langasek ]
* Refresh .pot file (and .po files) so that new UI strings are available
  for translation in LP.  LP: #425014.
