If tab stops are set, existing items in the list box are not invalidated

[Raimonds Praude]

If tab stops are set, existing items in the list box are not invalidated
(i.e., not automatically re-drawn.) after a new item is inserted.

LISTBOX_InvalidateItems( descr, descr->top_item ) function is called now
with a top visible item parameter if an item is inserted and if the list
box style is LBS_USETABSTOPS.
