Localization support for filesystem entries in Tracker and Deskbar (leaf menu). (It appears to work, but is likely incomplete and quite possibly incorrect.) Fix issue with RosterData::Refresh() resulting in a B_LOCALE_CHANGED broadcast, and Deskbar looping. Add a global boolean gLocalizedNamePreferred to avoid calling BLocaleRoster::Default()->IsFilesystemTranslationPreferred() too often from Model instances. Following Tracker code style in libtracker, so as to not mix in too much clean-up.
