UI Improvement: Show the person last committed or created the Merge Request with the user's avatar

Description

People are visual - but gitlab shows a lot of text. It would improve the UX, if we display the avatar of the user last committed to or created a MR in the List of Merge Requests. This is probably really easy as the API Call to a Merge Request gives me the user's avatar.

Proposal

At the moment, I have realized this with a Injected Javascript, but as this does one query to the server per line, it will not be a long term solution.
Note: I have also Highlighted the "WIP" with Javascript
