Changesets: Show review status and comment count when navigating between linked changesets

[danieldegroot2]

What feature would you like to see added?

Another minor suggestion;

When selecting an object and navigating between linked changesets, show review status and comment count, so user is aware if they (already) have review / comments. i.e. in case a revert changeset is reviewed good, user can check if previous changeset is reviewed bad and has feedback comment for user with bad changeset (in case a changeset is reviewed bad a user could theoretically check if the future/next changeset has good review,); for which I suggested adding a link in #835.

Why would this be useful to you or other users?

Allow users to more easily see if at least directly linked changesets might be relevant to current object status. (yes, there might be intermediate changesets and many changesets are not reviewed, of course.)
