Admin area

[TooAngel]

To be able to maintain the World Driven auto-merge certain 'admin' functionality needs to be properly exposed. I started already with /admin/logs which shows the logs from heroku.

My idea

Adding an admin link to the footer which opens a view that shows some statistics like a graph with requests, the current logs from heroku and everything else we need to maintain the service without superpowers. Everything needs to be read-only of course, because we only do changes via Pull Request.
