Add <a href='...' sapper-noscroll>

[Rich-Harris]

Occasionally you want a link to take you to a new route without affecting the scroll position (e.g. you're flicking through some horizontal tabs that have been pushed down by a header). Currently it requires some hoop-jumping.

It would be cool if you could just do this instead:

<a href="foo" sapper-noscroll>
  clicking this link won't reset the scroll position to zero
</a>

I just implemented a quick ad-hoc work-around, but it's annoyingly janky, since I have to persist the scroll position and the resume it every time the route changes. Maybe there's a better way to overcome the jank, but nevertheless this feature would be much appreciated!

This is implemented in 0.22.10

Just what I was looking for, thanks!
