fix: remeber scroll position when go to previous page, resolve #16

[ali4zimi]

I used localstorage to store previous pages with their scroll position. When the user presses the back button they will be at the same location where they left off. I worked on this solution today and it works now. Please check it once more

Thanks @ali4zimi

Why using the localStorage since the navigation is on client-side actually, why not using a variable in memory instead?

[ali4zimi]

Thanks, @Atinux for reviewing it, I assumed when the user refreshes on the next page, the variable in the memory would be cleared.

If he refreshed the browser will respect the position normally.

I actually wrote a library with @posva about this yesterday coincidentally https://github.com/antfu/vue-router-better-scroller

Thanks, great library! I needed this for one of my own projects.
