Robert Roebling 953704c1c7 Corrected wxlistBox, wxRadioBox, wxComboBox and
wxChoice in that they do no longer send events
    after programmatic calls
  Corrected wxStaticBitmap
  Reimplemented wxRadioButton as per wxMSW
  Updated docs for the above
  Update testconf for socket changes
  Other minor fixes
