-- Remove Finder's Icon in the Mac OSX Dock
-- This is useful if you want to keep Finder running alongside Path Finder,
-- but don't want to see it's icon in the Dock or in the list of running
-- applications.

-- Taken from Jampe's post on the Cocoatech forums:

-- If the dock is hidden, sometimes this doesn't really work
-- So show the dock before removing, and autohide it again afterwards
