Use Growl for Entourage notifications

See the following for Entourage 2004, and Entourage 2008 to turn off the stupid Entourage notifier and use Growl instead.

I made some modifications to the graphics so that the Entourage logo is red for critical and yellow for urgent instead of having little traffic signals over the big purple “e” so it’s a little slicker and I changed the location of the images to somewhere more discreet than the root of my documents folder, but the script works pretty well.
