    g_free() output of get_negative_color
    
    because gdk_rgba_to_string() returns a newly-allocated string
    
    * get_negative_color is gchar* instead of const gchar*
    * move to dialog-utils.c
    * rename get_negative_color() to get_negative_color_str() in
    window-main-summarybar.c
    * add g_free to gnc_tree_model_account_dispose ()
    * modify code to g_free () after use

    [gnc-budget-view.c] totals - 5 fundamental types
    
    previous showed income/expense/transfers/totals budget totals, of
    uncertain meaning. now shows income/expense/asset/liability/equity
    budget totals.
    
    the 5 lines also become sensitive to global sign-reverses property

Date:   Sat Oct 19 16:19:11 2019 +0800

    [budgets.c] handle both natural & reversed signs budgets
    
    introduce new API
    * gnc_using_unreversed_budgets - queries book's unreversed feature
    * gnc_reverse_budget_balance - check if book unreversal status matches
      2nd argument. if so, return account's reversal status. else, return
      FALSE.
    
    * gnome-budget-view can now show both natural and reversed budgets
    * gnome-plugin-page-budget will now read&write both natural and
      reversed budgets.
