1. added SetSelection() to wxItemContainer and removed its declarations

from derived classes
2. made wxItemContainer::Select() non virtual: it simply calls SetSelection()
3. renamed wxListBox::SetSelection(n, select) to DoSetSelection() for all
   ports and defined non virtual SetSelection() overloads in the base class
   to avoid virtual functions hiding
