Express Handlebars support

[joshnoe]

Any idea how to make this work with express-handlebars?

[joshnoe]

Figured it out:

let viewEngine = expressHandlebars.create({
        defaultLayout: 'main',
        layoutsDir: 'server/views/layouts',
        partialsDir: 'server/views/partials'
    });

HandlebarsIntl.registerWith(viewEngine.handlebars);

I'll gladly create a PR adding this to the ReadMe if it'd get merged?
