Add the ability to mark merge requests as read, and provide an indicator for post-read activity.
Created by: jleyrer
It would be helpful if, after viewing a merge request, I could mark it as read (or it was automatically marked as read). Then on subsequent views of my list of open merge requests, I could see an indication of whether or not there has been any comment activity on the merge requests I've read. This way, if I make comments that require follow-up from the merge request author, I could see at a glance if there is any reason to go back in and take a look.
Thanks!
