D7096: Only send active window changes to X11 root window if the X11 window changed

[David Edmundson]

  So am I wrong in thinking on X, our favourite method KWindowSystem::forceActiveWindow changes _net_active_window on the root window?
  
  My concern is:
  
  - Typing in client A
  - Client B does KWindowSystem::forceWindowActive()
  - User ignores it and selects client A again
  - Before this patch A gets definitely activated
  - After this patch, does it?
