Comment 7 for bug 2017034

I've found a much easier way to handle skip links in Angular using ViewportScroller instead of fussing with the router. It needed an offset to account for our fixed nav bar's height, but I like this much better.

New branch, same testing procedure (see comment #2): https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/sleary/lp1615707-staff-skipnav-v2
