[ZWeb] zope site updates

[ethan mindlace fremen]

Hi.

Every time something changes with zope.org I'm going to talk about it
here.  It might also make it into the ZWN if it's "worthy".

 * Products can be sorted by Author, Title, and Date, and are batched
into groups of 20.  Unfortunately, the default is unsorted.

 * Resources/MailingLists now lists all known Zope related mailing
lists, with the exclusion of portuguese/brasilian, because I'm asking
them to have only one zope list.  If I've missed any, let me know.
