Add optional 'author' param when making commits

This fulfills https://gitlab.com/gitlab-org/gitlab-ce/issues/20789 by adding the ability to specify a user's ID to be used as the author of a commit.

Fix processing of events when build finished.

Update pipeline after processing builds. Otherwise we can get into scenario where pipeline will be marked as running.

This solves a quite significant regression in Pipeline processing.

Proper fix is to move all this to Sidekiq Worker and process pipeline there.
I'll do it after 8.12 release.

Frontend for Merge Request Diff

This merge request improves the UX for the merge request diff feature which was recently implemented here (https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/6127). Specifically, it styles various parts of the diff feature to match the designs, it disables comment-related buttons in states where comments are disabled, and it adds a 'Show latest version' button for convenience.

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

I could use feedback on this MR's fidelity to the design.  

## Why was this MR needed?

Neccessary styling improvements for basic UX of this feature, and enabled comment buttons are not functional and thus need to be disabled in certain states.

## Screenshots (if relevant)

Fix "Unsubscribe" link in notification emails that is triggered by anti-virus

## What does this MR do?

* The unsubscribe link in an email body only unsubscribes automatically when logged in, otherwise the user is asked for a confirmation.
* The unsubscribe link in an email header unsubscribes automatically whether logged in or not.

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

This addresses all the comments from https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/5241, I think!

## Why was this MR needed?

People were getting unsubscribed automatically by AV software.

Fix broken spec due to last_activity_at updates being throttled

In https://gitlab.com/gitlab-org/gitlab-ce/builds/4218398, the build failed because the last_activity_at column was only being updated once per hour. We
can fix this spec by stubbing out the throttling and adjusting the spec to test the right event timestamp.
