GLUI_List can't find last item

initial report

1. make a GLUI_List called lbSeries, put 2 items in it
2. make a button that tries to perform an operation based the selected item's text
3. control_cb callback for the button click:
   int id= lbSeries->get_current_item();
   GLUI_List_Item* item = lbSeries->get_item_ptr(id);
   engine->DoSomething(std::string(item->text.c_str()));

Works fine for the 1st item in the list. For item #2, lbSeries->get_item_ptr(1) always returns NULL, even though the current item selected is id==1

This is because get_item_ptr works off id's (which are intrinsic to list items) while get_current_item returns an ordinal index.

The list API needs work.
