* use more GlazedLists stuff (EventList, AutoCompleteSupport) and remove obsolete classes (SimpleListModel, TextCompletion) * don't use SearchResultCache in EpisodeListClient (was only done for better ui interactions) * removed caching from ResourceManager * some improvements based on FindBugs warnings * use args4j for improved argument parsing * updated ant build script * more general MessageBus/Handler (use Object as message type instead of string) * ChecksumComputationService is not a singleton anymore * TemporaryFolder is always recreated if it is deleted by the user, or another instance shutting down * Notifications flicker less when one window is removed and the others are layouted * lots of other refactoring
