applicationNameForGrowl Return the name of this application which will be used for Growl bookkeeping. This name is used both internally and in the Growl preferences.
This should remain stable between different versions and incarnations of your application. For example, "SurfWriter" is a good app name, whereas "SurfWriter 2.0" and "SurfWriter Lite" are not.
You do not need to implement this method if you are providing the application name elsewhere, meaning in an auto-discoverable plist file in your app bundle (XXX refer to more information on that) or in the result of -registrationDictionaryForGrowl.
