Looking at the hyperdb project object wrapper methods, as described at
http://roundup.sourceforge.net/docs/customizing.html#hyperdb-property-wrapper,
there is a reverse() method and a sorted() method, but this
Roundup-hacking newbie didn't see a way to successfully combine both on
one object (if there is one, please enlighten me).

I have thus made a trivial change to my 1.6 installation to the sorted()
method to optionally return the items in reversed order.  I've attached
a diff of my changes, ported to the current development code, but
without testing.
