Removed the old rss and atom classes and scripts.  These have been replaced
with a single feed.php script and the feedcreator class developed by
Kai Blankenhorn and released under the LGPL.

A copy of the LGPL has been added to the doc directory.

Updated the database with new accepted values for the feed versions, as
well as updating the relevant scripts to accept those values.

Added ATOM 0.3 support courtesy of the aformentioned feedcreator class.

Cleaned up the paginator class, adding a method to specify total items
after initialization.  Also added additional comments to the class.

Updated the Copyright date on all files.
