  Fix for issue3559: No preferences menu in IDLE on OSX

  1) Add a comment to the help file to that points to the
     preferences menu.

  2) An earlier checkin tried to detect Tk >= 8.10.14,
     but did this in the wrong way. The end result of this
     was that the IDLE->Preferences... menu got surpressed
     when using the system version of Tcl/Tk
