This is a slightly different manifest that updates everything under the
GNOME umbrella, i.e. including "World" packages that follow a different
versioning scheme, some of which are more experimental than gnome
itself.

I'm not sure how useful this feature will be, given that the gnome-
metapackage refers to packages with different versioning schemes
already.  I do think we need a way to distinguish unstable versions for
those packages that still follow the old versioning scheme as well.

The idea is that with a recent enough gnome-shell updating the
extensions can be done with a single command, without affecting other
packages.  Since extensions don't have common versions, it only ever
makes sense to pull the latest when gnome-shell is the latest as well
(or at least close to it).

Cheers
