Should work as a direct canonical URL now... the updates may not have
made it through to everyone, so I haven't made the old URL into a
redirect just yet; both
textbooks.wikipedia.org and
wikibooks.org should
access it directly.
I've also set up WikiBooks as an interwiki prefix on all the wikimedia
wikis, it uses the new address.
