[typo] Extended_html

[Nic Lindh]

I just updated my blog to the latest svn trunk and am getting
extended_html errors. There's a migrate script in /db/migrate, which
looks like it'll do the job of adding the required fields to the
articles, but my mind is utterly melted and I simply can't figure out
how to run it.

If any of you could please help me out with the magic incantation it
would be *hugely* appreciated.

Thanks a bunch,

Nic
