 Changes for 0.9.16:
 *06/04/16:
+   * Set (take|send)to(next|prev)workspace offset default value to 1
+     instead of the current 0 (which makes them look non-functional).
+     Similarly for tab and (|next|prev|left|right)workspace.
+     - Thanks Jonas Koelker (sf.net 1467926)
+     FbCommandFactory.cc
    * Add "CloseAllWindows" key binding 
      (thanks Adriano Dal Bosco - adbosco at users.sourceforge.net)
      - Useful to trigger all "close" actions before flux exit (or other)
