REVISION SUMMARY
  Dolphin needs to figure out whether or not kio-stash is installed
  to set the enabled state of a UI action.
  
  When KProtocolInfo::isKnownProtocol can't find a protocol it gets
  worried its protocol cache might be out of date, so it rebuilds it
  (doing plenty of disk I/O) and looks again. kio-stash is currently
  not yet installed on many systems, so this means most Dolphin
  startups out there.
  
  This patch switches to using QDBusConnectionInterface::isServiceRegistered
  instead to determine whether the stash notifier daemon is running,
  which should be faster than doing disk I/O.
