Subject: - Patch #3986 by James (and Boris :)):consolidated all feed-related
 settings in one place.

* adds a "feed settings" section to admin/settings where 2 new settings are introduced:
* number of items per feed
* default length of feed descriptions (title only, teaser, full)
* patches all of core to obey the above - including the new aggregator (out) feeds
* adds support for adding namespaces in _nodeapi('rss item') - which means things like iTunes RSS and yahoo's media rss can be implemented by the appropriate modules (i.e. audio.module)
* includes some additional info in the default node feed - specifically the element (links directly to comments) - and dc:creator - to show node author information.
