Display repository activity level #1920

When I browse for existing solutions on Github it happens quite a bit that I find something that seems to fit the bill only to notice later that there hasn't been any activity on that project in years.

It would be nice to have a banner / notification in that case that displays, that I am currently viewing an inactive repository - as this keeps me from checking various branches for any commit history.

This notification could be displayed on a repositories page, similar to what GitHubs archived projects does. Maybe something like: 'You are currently viewing a repository that hasn't seen any activity in a while'.

If a banner is too noisy an alternative could be a simple badge next to the repository name (where refined-github currently also displays the build status).

The only question is when a repository should be considered inactive - I personally would consider a repository without any activity (no new commits on any branches, no closed issues, ....) in the last 3 years inactive, but I guess that's up for debate :)
