Important change: ptrArrayAppend() is now implemented in terms of ptrArrayInsertBefore(). ptrArrayInsertBefore() can safely insert at the first invalid index; ValleyBell helped ensure this. tabAppend() will also be implemented this way; boxAppend() might be if uiBoxInsertBefore() becomes a thing. We can rename InsertBefore() to InsertAt() now too.
