tdf#148737 improve tooltip for Arrow Styles icon

   Have used "arrowhead" in tooltip in anticipation of
   the intention to move away from using "Arrow Styles"
   in the Line dialog (and possibly to use "arrowhead").
   Also, the dropdown box for this icon uses "Arrowheads",
   so the choice would be consistent and understandable
   in its context, and may make it unnecessary to
   change the tooltip with any future reworking of the
   Line dialog.
