When using the file links in diffs that had multiple pages, the scroll position

would jump to the file, but then the diff viewer would immediately reload on

page 1. The issue here is that we were setting location.hash in order to update

the displayed URL to include the page number, and the backbone router was

interpreting that as an indication that it should reroute.
I've changed it to use router.navigate() with trigger: false. This updates

the displayed hash without actually triggering any routing.

Created a giant multi-page diff and loaded page 2. Clicked on a filename in the

file list. Saw that it jumped to the file and updated the displayed URL

correctly, and did not navigate back to page 1.
