[Merge] ~mwhudson/livecd-rootfs/+git/livecd-rootfs:language-support-in-catalogs into livecd-rootfs:ubuntu/master

one extra sidenote which isn't new to the change but 'no_lang_seed' is a bit of a confusing naming since it refers to the default layer and not the no-language one which removes the default language right?
