Added some modules from Riaan Booysen:

* wx.lib.flagart:  contains icons of the flags of many countries.

    * wx.lib.art.img2pyartprov: makes images embedded in a python file
      with img2py available via the wx.ArtProvider.

    * wx.lib.langlistctrl: A wx.ListCtrl for selecting a language,
      which uses the country flag icons.

    * An I18N sample for the demo.
