OmniGrowl 3.9 released, focusing on iTunes artwork

OmniGrowl 3.9 has been released. Changes focus on iTunes artwork. Better quality images are downloaded from discogs. Additions and improvements to Immediate Actions and plugins and other tweaks make Omnigrowl play even nicer with GeekTool 3. With some set-up, the changes make OmniGrowl a more useful tool to relatively passively set missing artwork in iTunes. In addition, the documentation has been revised and reorganized, and moved entirely online. As always, please see the version history for details.
