site title dupplication on tags and category

Hi guys !

Well, another congratulation for this killing plugin. one site I manage have been referenced in 25th position with keyword "horsenality" with only 2 mentions of the word in the text on one article... in... 4 minutes ! Oo

Almost before the official parelli site. Killing loooooooool !

Well, still a problem of site title dupplication when :

- SEO options are not filled in
- on tags and category pages : for example.
