enhancement request: integrate with vue-router

[chrisbraddock]

Similar to vue-analytics, allow passing a router instance as an option:

import router from './router'
import VueFacebookPixel from 'vue-analytics-facebook-pixel'

Vue.use(VueFacebookPixel, { router })

and automatically fire 'PageView' on route change

Sure thing, thanks!

PRs are welcome, if you are interested!

If I get to it before you, for sure. :)

According to Facebook Pixel documentation, all changes in the history state is automatically tracked as a PageView. Perhaps this feature is significant only in the cases when router is used in hash mode.

By default Facebook Pixel activates the HTML 5 History State API listener. This means that each time a new state appears in the history, such as history.pushState, Facebook Pixel fires a PageView event. Note that due to the way we designed Facebook Pixel's JavaScript code, you cannot fire more than one PageView event explicitly without this listener.

@rafapg do you have any opportunity to investigate this?
