Merged r1-2096 of questsystem5 back to trunk

I hope there weren't more "hidden merge changes" in r2909 than the one in OverlayGroup (removeElement) (and related to this the adjustments in NotificationQueue).

The corresponding media commit seems not yet to be done, but it doesn't break the build.

  • Property svn:eol-style set to native
  • Property svn:mergeinfo set to (toggle deleted branches)
