Add useful error pages

[dvidsilva]

At least for 404, right now it doesn't show any useful information, a simple empty page with the layout, logo and link to homepage would be great.

I would like to give this one a shot. Just to make sure I am headed in the right direction, you would like to add more info to the 404 template and possibly the error template?.

Could you specify a little more about the layout?

Yes, this is it. You can modifiy it so it looks better, and add better error messages. Is currently kinda working

The code is around index.js, like:

app.use(function(err, req, res) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render('error');
});

There's a few answers in SO like this, but I think something like this code from routes/index.js might be enough:

 return res.status(404).render('404');
