Merge branch 'im/menu' of https://github.com/imciner2/wxWidgets

Make wxEVT_MENU_HIGHLIGHT generation when there is no highlighted item
consistent across all the major ports: use wxID_NONE instead of wxID_ANY
in wxGTK and send these events, which were previously not sent at all in
this case, in wxOSX.

See https://github.com/wxWidgets/wxWidgets/pull/1637
