feat(scroll) - WIP - allow a different scroll element other than window

[phouri]

Still a WIP - just to make sure I am on the right track before fixing flow / e2e / unit tests.

This works (for me locally), let me know what you think.

Fixes #2777

First time I am using Flow - so probably did some stuff wrong, let me know if you see anything obvious.

If this is fine - I will proceed with fixing flow and creating new tests.

Thanks for working on this ref https://github.com/vuejs/vue-router/issues/1187

I will come back to you when I can to review the api, this is the kind of thing that would nicely fit an RFC :)

@posva, can we expect this pull request to be brought into life and reconsidered? Very, very useful feature I cannot find a workaround to at the moment :/
