Growl for Entourage (via Applescript)

So I went looking for a way to connect Microsoft Entourage (yeah, I’m in Exchange land now) with Growl for notifications. In theory, there are many ways, all of them Applescripts. In practice, I couldn’t find one that worked properly … so I grabbed the best one I could find and hacked it from there. I’ve put it in my public subversion repo, so if you need it either ctrl-click and download or use svn to nab it.
