New theme 'blix'

Thanks to lordcoffee from our forums, we now have his new ported theme (original theme created by Sebastian Schmieg) called Blix in our Spartacus/CVS repository. It should be available within the next few hours. Users who can't wait can already download the theme from the forum's link above.

Many thanks for keeping the theme contributions coming in so many and often, all you guys! It's great to show how great and flexible the Serendipity templating technique actually is. :-)
