[themes] themes.drupal.org upgrade

[Bèr Kessels]

Thanks for the offer.

Right now there are several tasks open. Because you told that you are not 
interested in theme testing, here are the things that need "TLC" codewise:

* Themeswitcher has a next-previous block. Somehow that does not show the 
screenshots (anymore). 
* The next and previous links dissapear for the one-but-first  and the last 
theme. Something in my code is very wrong, but I cannot find out what is 
wrong.
* There is no big overview of all the themes anymore. If you browse in the CVS 
history you'll see that I ripped it out, because it gave problems. But 
something like an overview would be great. (eventhough /i/ beleive that 
giving an overview of all themes is the task of Drupal.org project module!)

themeswitcher is here:
