Aggregator Reloaded

The ICANN blog aggregator has been rebuilt from scratch. Besides being much simpler and more efficient than the old code, the new code also leads to a shorter delay until updates about which the aggregator is notified by a weblogs.com-style ping are actually incorporated. The most visible changes are probably the re-direct to the script that generates the index page dynamically, and the changed layout. Any comments welcome. Remarks about the layout are only accepted, though, when accompanied by a new style sheet.
