Add a new wxUSE_STD_CONTAINERS_COMPATIBLY option.

This option, which is on by default unless the use of STL is disabled,
provides better interoperability with the standard library when it can be done
without breaking backwards compatibility.

The first example of its use is to allow passing std::vector<> of any string
compatible type to wxItemContainer::Append(), Insert() and Set(), allowing to
directly initialize various wxControls deriving from it such as wxChoice,
wxComboBox, wxListBox from a std::vector<> of strings.
