browser_side: classes reorganisation: - moved widgets in dedicated modules (base, contact, editor, libervia) and a widget module for single classes - same thing for panels (base, main, contact) - libervia_widget mix main panels and widget and drag n drop for technical reasons (see comments) - renamed WebPanel to WebWidget
