D7995: KDevelop: address dirwatching inefficiency (WIP/PoC)

[René J.V. Bertin]

  updated to fix the potential signal delivery to a stale watcher instance.
  
  This new approach watches only directories and will thus trigger a full reload of any directory in which something changed. It would be pointless and potentially counterproductive to do this just before all projects will be unloaded; prevent this by connecting `KDirWatch::stopScan()` to  `QCoreApplication::aboutToQuit`. This should be safe, right?
