Next and Previous commit buttons in merge requests

At the moment, if I want to review Merge Request on commit basis (one commit after the other) I have to open each commit from commits tab which is not very usable, as I have to go back and forth. It would be very convenient to review every commit in one continuous flow.

Proposal

• add simple buttons Next commit and Previous commit buttons
• add keybindings to switch between commits
  • n for next commit
  • p for previous commit

As far as I remember gerrit have similar functionality, but probably concerning files as generally it's more commit focused.
