Make use of $router global safer.
Code breaks if something that isn't a vue-router inhabits the global Vue var "$router". For example, I'm using a different router and it installed itself to the global name "$router" but it doesn't have a beforeEach method. I don't think "$router" has been reserved specifically for vue-router or any router implementation.
