ItemUnderAt was returning items that were not under the superitem (this was fixed for EachItemUnder in hrev52210). Make a NULL superitem mean the parent of the topmost items. Despite not being explicitly documented in the BeBook, that's how BeOS works, the MenuWorld test app uses it and, well, it's handy.
