[typo] Bug in BrownType

[Jens Alfke]

I've found a bug in the BrownType theme, and I can't find an email  
address for Todd Ericksen anywhere, so I'll report it here; I hope no  
one minds.

The theme won't display the 'extended content' of an entry. What you  
see on the permalink page is just the same as on the front page, so  
if you break your posts up with a short intro and the rest in the  
extended entry, the readers won't ever be able to see it.
