use direct callbacks instead to handle history and workspace list updates * history-docwidget.h, history-dockwidget.cc (history_dock_widget::_update_event_enabled): Delete data member and all uses. * history-dockwidget.cc (history_dock_widget::construct): Don't install a timer. (history_dock_widget::update_history_callback): Now public. * workspace-model.cc (workspace_model::workspace_model): Don't install a timer. (workspace_model::_update_event_enabled): Delete data member and all uses.
