With help from a combination of sbrabec and darix, I've fixed the lion's share of the Expansion Errors we'd been seeing on GNOME:Community/openSUSE_10.?+GNOME_[UN]STABLE by tinkering with the project metadata. This means that a raft of packages that wouldn't update if you had one of those variations of G:C setup in $PACKAGE_MANAGER will now be upgraded the next time you update.

Forgot to mention yesterday, changed the flag for the default edition of Planet SUSE from a US/UK combo to the UN to indicate that it's not just English but any language other than German or Spanish.
