* moderatedcomments: Added moderate_pagespec that can be used
to control which users or comment locations are moderated.
This can be used, just for example, to moderate http://myopenid.com/*
if you're getting a lot of spammers from one particular openid
provider (who should perhaps answer your emails about them),
while not moderating other users.
* moderatedcomments: The moderate_users setting is deprecated. Instead,
set moderate_pagespec to "!admin()" or "user(*)" instead.
