Re404 - move 404 error handler at the end of routing

common-route.js

Page404 = function (req, res, next) { res.status(404).render('page404', { title: "Oops 404!" }); }
app.re404 = () => { app.remove(Page404); app.use(Page404); }
app.re404();

// and call app.re404() function after adding new routes (eg. when loading submodules)
