fix scrolling on chrome >= 61 by updating localScroll and scrollTo

Discussion

Anchor scrolling on solid.mit.edu doesn't work for Chrome 63 (and probably not for Chrome>=61, when the scrolling element is no longer the body but the document element).

The maintainer of jquery.localScroll and jquery.scrollTo recommends updating the later version of both packages in flesler/jquery.localScroll#38.

After updating localScroll and scrollTo to their latest release versions (2.0.0 and 2.1.2, respectively) from 1.2.8b and 1.4.3.1, anchor scrolling works in Chrome.

I have this issue on my website. I just don't know how to update to the latest versions.
