Fix clicking on move flags in the diff viewer.

Move flags haven't been clickable in a while. They were still calling
the old RB.scrollAnchor function. Now, clicking emits a moveFlagClicked
event, which the page listens to and scrolls to the matching anchor for
the other end of the move range.

Clicked move flags on both ends of ranges. The page scrolled, and the
chunk selected.
