Resolve "Highlighting lines is broken"

## What does this MR do?

Add line highlighting back to diff view.  This was working in the MR "changes" tab, but not on a commit page such as https://gitlab.com/winniehell/reproduction-area/commit/9101e66f5761929002956e0f2dd65d7f8643903d

~~This MR also fixes the `scrollToElement` method in `MergeRequestTabs` to account for the extra height of the tab links which are now fixed in place once they are scrolled to the top of the screen.~~ (removed in favor of !7051)

This MR also refactors much of the `Diff` and `MergeRequestTabs` classes to es6 syntax in an effort to increase readability.

## Are there points in the code the reviewer needs to double check?

Check out both MR "change" tabs and commit diff pages and ensure that line highlighting works and that loading a page with one of these permalink hashes correctly highlights and scrolls to the line.

Ensure I didn't break anything in the transition to es6 syntax.  Check the functionality of the tabs on MR pages, as well as diff page interactivity (unfolding hidden lines in diff files, adding comments to diffs, etc).  I have checked these myself, but another set of eyes would be a good idea.

Fixed row margins on Pipeline Settings page in order to unify styles

On the ```project-name/pipelines/settings``` page, I removed the ```.row``` styling on ```.build-status``` and ```.coverage-report``` as it was causing those rows to not have the same margins as the "CI/CD Pipeline" row.

Now, they are even as you can see below:
