[Zope-CMF] simple what's new box

[marc lindahl]

I did a simple what's new box... just needs two dtml methods in your skin
and adding whats_new_box into your default index_html. Code is
http://cmf.zope.org/Members/bowerymarc/recent_stuff.dtml/file_view once it's
published.

Cool thing is, cuz the way the catalog works, it shows you the new things
that you can actually access, which of course changes based on permissions &
logged in status.

I did this so that members of my engineering site can automatically see
anything that changed among the various projects that they have local roles
for (http://bea.bowery.com)
