More Backend Updates and some Tidy-ups

[Jim McDonald <Jim mcdee net>]

Hi,
   I've updated a couple more backends, at this stage I don't know if
the other backends were functional before the change to the resultsets,
so if anyone has a backend that they has not been converted to
resultsets and thinks it should be in 0.1 it might be best to say now.

   I've also made the resultset code a bit more resiliant by doing lots
of null and duplicate checking.

   Thanks to Kevin Godby for testing the addressbook update.

Cheers,
Jim.
