Make explorer's available views widget a pure React component
This new react component ReactAvailableViewsWidget will be part of the packages/react-components. It can be used in other web applications independently from Theia. It listens to the AVAILABLE_OUTPUTS_CHANGED Signal to update the widget. Signed-off-by: Bernd Hufmann <Bernd.Hufmann@ericsson.com>
