Change tui_which_element::data_window to be a pointer

Browse Source 
A coming patch will add a constructor to tui_gen_win_info.  However,
because the tui_which_element union contains an object of this type,
first something must be done here in order to avoid having a union
with a member that has a constructor.  This patch changes this element
to be a pointer instead.
