[TxMt] Blogging Bundle - Typo errors

[Benjamin Jackson]

First, upon posting a new article, I got an error that this line (510  
of blogging.rb) was trying to mod a frozen string:

       filename.sub!(/\.[a-z]+$/, '') if filename

Commenting that line out, I still got a 301 error from the script.  
I'm pointing it to

Anyone have any answers? Thanks,

Ben
