[gnc-budget-view.c] modify GList in reverse

Browse Source 
because the GList modification in gnc_budget_view_refresh works on the
tail end (see g_list_last being chopped off successively, followed by
g_list_append successively), wherease it's much faster to work on the
head end. Therefore: reverse, modify, and re-reverse.
